Video: How to set the date and time on your smartphone?

I remembered that, together with a work colleague, I had long ago solved this problem on Android (HTC Hero) and wanted to write in the sandbox, but kept putting it off until later. And today another article “Updating time zones on Android” appeared, which practically buried the idea of ​​writing and confirmed the idea that there is no need to put off important things for later. But... after remembering a little, I finally decided, because these articles discussed problems associated with the transition to winter/summer time and did not touch upon the issue at all regarding the operation of the clock widget with the weather and automatic determination of time through a cellular operator.

It all started when I was purchased new phone HTC Desire S.

During the setup process, it turned out that in the date and time settings there is no option to select my city - Novosibirsk and I have to select an alternative city with a suitable time zone.
It also turned out that time synchronization from the operator works somehow mysteriously and the HTC Clock widget in weather display mode and turned on automatic synchronization displays incorrect time.

The picture may seem like everything is fine, but the time on the phone has actually run back an hour. You can turn off automatic detection and set the zone manually, but then we get the following:

As you can see, Novosibirsk is not on the list. We had to choose Bangkok, while system time in the phone it became correct, but the widget still displays with an offset of an hour ago.

We tried to find a solution online. We discovered that we are not alone, and similar problems exist not only among residents of Novosibirsk, but also among residents of other cities on the planet. We have not found a comprehensive solution to all these problems.

We could ignore all this, turn it off, use our hands and not pay attention to the widget, but... this is Android - and this means that we can and must defeat it!

And so, we begin

We found an application through osmonitor in which the time zone is selected - (com.android.settings). We looked at the sources of the com.android.settings package and found out that the resources are loaded from XML file timezones.xml.

Got the apk of this application /system/app/Settings.apk with the following command:
adb pull /system/app/Settings.apk

I won’t describe all the details of how APK manager works and Android SDK tools, I think interested people can easily figure it out. I will dwell only on the key points.

WITH using APK manager performed the following actions

• decompile
• edited the files manually in another window
• compile. When compiling APK manager asks the following questions:
  “Is this a system apk (y/n)” – answer yes
  “Aside from the signatures, would you like to copy over any additional files that you didn’t modify from the original apk in order to ensure least # of errors (y/n)” - we also answer yes.
  Next, we follow the instructions suggested by the APK manager, in another window we delete from the keep directory the files that we changed + resources.arsc.
• We complete the assembly.

The resulting apk was placed back into the phone:
adb push Settings.apk /system/app/

By doing this, we ensured that Novosibirsk appeared in the list of manual time zone selection.

Our city appeared on the list, but the definition of the time zone in automatic mode still didn't work correctly. To do this, we went further and found out that time zone settings for cities are stored in the database, namely in the file /system/etc/WPDB.zip.
Having taken it out of the phone using the same adb, we extracted two databases from it

• WP_0409WWE.db
• WP_0419RUS.db

In order for all the changes made to take effect, reset the application cache
Clock, Settings and Weather Provider. Well, just to be sure, we restarted the phone.

Results

As a result, we got these pies:

As we can see, in automatic mode the zone is determined correctly, the system time and the time on the widget are the same, and in manual mode Everything is fine.

Having become involved in a war against time, we decided to go to the end. Namely, to solve the problem of canceling the transition to winter/summer time.
Downloaded the latest tzdata (aka timeinfo.dat) from a then-available resource

Hardware problems

The battery needs to be replaced. To do this, turn off the computer from the network and disconnect the power cable from system unit.

Make sure your computer's power supply is powerful enough. In some cases, due to the incorrect selection of this element, the computer may malfunction, causing it to display the wrong time.

If, even after replacing the battery, the time is still set incorrectly, contact a technician: the problem may be due to an outdated motherboard, which is out of order or conflicts with newer equipment.

Problems with the operating system

Make sure you have set your time zone correctly. Typically, these settings are entered when installing the system, but you can also set them later by double-clicking with the left mouse button on the clock in the lower right corner of the screen and going to the “Time Zone” tab. Remember that if you set the wrong time zone, the system will automatically set the time corresponding to it.

Viruses may be the cause of incorrect time setting by the system. Check your computer's hard drive and removable media antivirus program and delete all malicious objects found.

Check if any software is messing up the time. Some programs have their own time settings and, after installation, configure the system to suit their needs, ignoring the settings set by the user. It is advisable not to install suspicious applications downloaded from suspicious Internet sources on your computer.

There are several reasons for this “temporal anomaly” to appear in the tablet. And believe me, if the time is lost, it’s unlikely that the tablet has forgotten how to count.

List of main reasons why this happens and solutions

1. You turn off the tablet at night, for example, to save battery. A very common reason, and the only way to get the time to work correctly is to stop turning off the tablet without a good reason. This is not a laptop or a TV.
2. If your tablet is equipped with a 3G module and a SIM card is inserted into it, remember where you bought the SIM card. Perhaps you bought a card in another region, where there is a different time zone. And if you have a checkmark in your settings “Network date and time”, this means that the tablet is set to the time specified by the operator settings in the region where the SIM card was purchased. The solution is to uncheck this box and set the time manually.

1. “Bad” firmware. If you have dabbled with flashing your tablet, it is quite possible that the firmware you installed contains some kind of bug. Solution - flash with official software.
2. The problem may be the device itself. They say that Chinese tablets swirling over time is quite common. The ClockSync application will help in the fight against this disease (requires ROOT rights to work). This program will allow you to set up automatic time synchronization via the Internet, the main thing is in the date and time settings, uncheck the “Network time zone” item, and set the correct time zone that corresponds to your region.

Many modern users People no longer use phones for hours, because the gadget is always at hand. It is important for them that the date and time are set correctly, since failures can lead to late awakening for work and constant delays. Therefore, every user needs to know how to set the time on an Android phone.

Incorrect time on the phone - why does this happen?

Even after setting the date and time very accurately, you may find the clock on the screen showing incorrect information. Before you enter new information, you need to understand why the time on your Android phone is lost. If you do not find the reason, then entering new data will be useless.

There are several situations when time is short Android phone Synchronization of date and time is lost. First of all, this happens if you decide to use network data. When traveling around your region or in populated areas located on the border of time zones, you may encounter that the time information is unexpectedly lost. In this case, it is enough to disable synchronization with the network in the date and time settings using the movable sliders.

Another reason why the time on your phone gets lost is software glitch. This may be due to the installation of some personalization applications, such as new clock widgets. The only way to fix the problem is to reset the settings to factory settings. Before performing it, copy the necessary data.

How to set date and time?

After you have become familiar with the main causes of failures, you need to learn how to set the time on your smartphone. To do this, you just need to follow simple instructions:

1. Go to the main menu, where all applications are collected.
2. Among the icons, find the image of a gear, entitled “Settings”. Enter it.
3. Among all the sections, you must select the one entitled “Date and Time”. In some versions of the operating system, this menu item is located in a larger directory - “Device”. Sometimes date and time settings can be hidden in the "Advanced Options" folder.
4. Once you have found a place with the necessary settings, you need to make changes to the current date and time values. You can also change the time zone and adjust the data display format.

There is no need to reboot the device; immediately after confirming with the “OK” button, the new data will begin to be displayed in widgets on the screen and in the status bar.

There is another way to change time settings

To do this, you can use the clock application, which manufacturers often place in the “Tools” folder. The algorithm of actions in this case is as follows:

1. Go to the application.
2. Go to its settings options. They are hidden behind three vertical dots or a gear icon.
3. Select "Change date and time". It may also be titled “date and time settings.”
4. Use the visual dial to change the current value.

The disadvantage of using the application is that you cannot change the display format or time zone.

What to do if the time on your phone is wrong?

If you are trying to install required parameters, and they are reset, then there may be several reasons:

1. You have synchronized the time with the parameters, specified by the network. In this case, before making changes, you need to remove the marker or move the tab from the “Use network date and time” item. This can only be done through the system settings menu.
2. A single software failure can be resolved by rebooting the device. If it does not help, then you need to completely reset the user settings.
3. Defects in the device’s firmware appear from the first days of its use. You can replace it yourself software or contact the service center for help.
4. The time zone set on your smartphone conflicts with the SIM card settings. In this case, it is worth changing the time zone to the one recommended by the network, and then setting the necessary parameters and disabling synchronization.

In some cases, to resolve the conflict between the settings of the smartphone and the SIM card, it is necessary to take more complex actions. First of all you need to save necessary files, remove the SIM card and reset the settings to factory settings. Only after this you need to disable synchronization with the network and set the desired date and time parameters.

Please note that resetting to factory settings on devices with open root access may destroy the custom firmware.

Using auto-sync time and date

If you want to have a gadget with the exact time at hand, then you need to use synchronization. There are two ways to get exact time on the screen of your smartphone - use standard capabilities or use applications for smart synchronization.

Regular auto-sync is enabled in the settings. You need to activate an item with one of the names:

• automatic date and time;
• use network date and time;
• synchronize with the network.

But please note that after activating this option, you will not be able to manually change the date and time settings. This option is also not particularly accurate - the average error is about 500 milliseconds.

Smart time synchronization using your phone app

Smart synchronization is enabled using applications. To carry it out, it is necessary to intervene in system settings Therefore, such programs require “superuser” rights. They won't work without them. All smart sync apps have a similar interface. Let's look at the principle of managing them using ClockSync as an example. This application has received positive ratings from many users. You need to work with it according to the instructions:

1. Download and launch the application.
2. On the main screen you will see the current time set on your smartphone, as well as a more accurate value delivered from a special server. Typically, the difference in data can be more than 20 seconds.
3. Use the buttons at the bottom of the screen to call context menu(usually the icon of several sticks or windows located on the right is used for this).
4. Click on the “Synchronize” menu item.
5. The application will ask you for root access. Allow him to change system settings using the “Grant” button.
6. After synchronization, there should be no discrepancies in the data on the main screen - the third line should contain the value “0”.

If you have normal firmware, which does not give superuser rights, you must change its settings before using the application. To do this, call the context menu and select “Settings”. The very first line in it will be to enable mode without. Place a marker next to this line.

How to place a clock on the home screen?

Now let's figure out how to set the time on the phone screen. Reading it from the status bar is not always convenient, so you need to display a large and convenient image on the desktop.

Almost all smartphones have a clock widget on the main desktop. If it was accidentally deleted, you need to return it:

1. Open the desktop of your smartphone. Find a place on it that is free from shortcuts and widgets and press and hold it with your finger for a long time.
2. A screen menu will appear in front of you. You need to select the “Applications and Widgets” item.
3. Of the two tabs, select the one entitled “Widgets”. You will see several options for sketches of visual additions. Find a watch among them.
4. Touch and hold the clock image with your finger. The desktops of your smartphone will appear in front of you, and with a movement of your finger you can move the visual module to any of them.

Beautiful clock widgets for Android

To change the data displayed by the installed module, use the instructions on how to set the time on your watch or phone. Children's widgets, as well as unusually designed clocks, by default in operating system No. To change the visual design of this module, you can download one of the applications:

• "Transparent Clocks and Weather";
• Sense Flip Clock & Weather;
• Sense V2 Flip Clock & Weather;
• Retro Clock Widget;
• DIGI Clock.

In you can find other applications with a wider range of modules.

You can also display a clock widget on the lock screen. To do this, you need to go to the system settings, select “Screen” from them, and then stop at the “Lock” item. In it you need to choose the option “Display time and date on the screen”. Here you can also allow the use of widgets, and then personalize the “curtain” using a standard or pre-downloaded utility.

Now you know how to set the time on your phone. Share the information you receive with your friends. If you or your loved ones have problems setting the date and time, and you could not solve it yourself, ask questions in the comments.
