Correct display of date and time is a fundamental function of any operating system, including the mobile platform Android. In the seventh version of this OS, known under the code name Nougat, the synchronization algorithms have been significantly improved, but users often need to manually interfere with the operation of the system clock. This may be due to frequent trips to other regions, the desire to use specific application functions, or simple failures in the network protocol NTP.
Incorrectly set time can lead to a number of critical problems: from the inability to connect to secure sites due to security certificate errors to incorrect operation of instant messengers and social networks. In this article we will analyze in detail all the available ways to change time parameters on devices running Android 7.0 i 7.1. You will learn how to disable automatic synchronization, how to set the exact time manually, and what to do if the settings are constantly reset.
Automatic synchronization and network time
By default, the system strives to keep the time up-to-date without user intervention, using data from a cellular operator or Wi-Fi network. This mechanism is called automatic date and time. When this feature is active, the device regularly polls time servers and adjusts its internal clock. For most users, this is the most convenient option, as it eliminates the human factor and errors when switching to daylight saving time.
However, automatic settings do not always work perfectly. When roaming, the phone may pick up the time zone of the host country, but leave the home time, which creates confusion. Failures are also possible if the network signal is weak. To check the synchronization status, you need to go to menu Settings → Date and time. Here you will see a switch responsible for using network data.
If you notice that the time is behind or in a hurry, the first thing you should try is to force a data update. To do this, you can temporarily disable and enable the option Use network time. Sometimes the system takes a few seconds to re-request the server. In some firmware from third-party manufacturers, such as Xiaomi or Meizu, this item may be called differently, for example, “Synchronize with the Internet.”
⚠️ Attention: If you often travel between time zones, leaving it on Setting the time automatically may result in alarms not going off at the time you expect, as the system will change the time zone as you move.
Manually setting the date and time
When automatic mode is not suitable or is not available, manual control of the settings is the only solution. This method gives you complete control over what is displayed on the lock screen and status bar. To access manual input, you will need to first deactivate automatic sync. Without this step, the input fields will be blocked by the system.
The change process is as follows: after disabling the "Auto" checkbox, the "Date" and "Time" items become active. By clicking on them, you will open a standard selection interface where you can scroll through the values to the desired indicators. If you moved the hands an hour forward, but left the Moscow time zone, then at the next automatic synchronization the system will return everything as it was.
For accurate installation, it is recommended to use the reference time, for example, from another device or voice assistant. Please enter information carefully, especially if you change the year or month, as this may affect the sorting of photos and files in the gallery. Some applications that use license keys with a limited validity period may stop working if the date is set in the past or far future.
☑️ Preparing for manual setup
After making changes, the system may require confirmation of actions. In older versions of firmware based on Android 7 sometimes there is a bug when, after manually setting the time, it is reset upon reboot. If you encounter such a problem, check the battery charge of the main battery, as if it is deeply discharged, the BIOS-like chip settings may be lost.
Managing time zones
The time zone is a critical parameter that determines the time offset relative to Greenwich Mean Time (UTC). Unlike the clock itself, the zone specifies the rules for daylight saving time and historical time changes in a particular region. Android 7 the list of available zones is extensive and includes not only major cities, but also specific regional areas.
If you are in a border area or use the phone to work with clients from other countries, you may need to change the belt manually. This is done in the same menu Settings → Date and time, in item Time zone. Select a city that has the same time as your current location. The system will automatically calculate the required offset.
There is a nuance associated with summer time. Some countries have abandoned seasonal switching, while others continue to do so. Android's time zone database is updated with security patches. If your phone hasn't received updates in a while, information about daylight saving time rules may be out of date.
Why is it important to choose the right city in the time zone?
Selecting a specific city (for example, Moscow, and not just GMT+3) is important because the database contains the history of time changes for that location. This ensures that applications working with archived data or schedules will correctly display the time of events that occurred several years ago, taking into account the rules in force at that time.
For developers and advanced users, it is possible to view the current offset in minutes through developer mode or special terminal applications, but for an ordinary user it is enough to select the correct city from the list. Make sure that after changing the zone, the time is updated correctly and there is no desynchronization with network services.
Changing the time format: 12 and 24 hours
One of the most common user requests concerns the time display format. Some are accustomed to the classic 24-hour format, adopted in most CIS countries and Europe, while others prefer the 12-hour format with the designation AM (before noon) and PM (after noon), popular in the USA and Great Britain.
V Android 7.0 this setting is placed in a separate menu item, usually located at the very bottom of the section with date and time. The switch 24-hour format allows you to instantly change the way the clock is displayed in the status bar and on the lock screen. This change applies globally to the entire system, including widgets and third-party applications that follow system settings.
It is worth noting that some custom skins, for example MIUI or EMUI, may have their own themes that ignore the system setting time format. In this case, you will need to go to the settings of the theme or specific clock widget on the desktop and change the setting there. Standard Google applications, such as Google Clockalways adapt to the system format.
Changing the format does not affect the internal calculation of time by the system. For the processor and applications, time is always stored in a single standard (usually Unix-timestamp or similar), and formatting occurs only at the stage of displaying information to the user. Therefore, you can safely experiment with the settings without fear of breaking the work of the calendar or alarm clock.
Problems with desynchronization and their solutions
Often users are faced with a situation where the time on the phone lives its own life: it can suddenly jump forward several hours or lag behind by a day. Most often, the reason lies in a conflict between network synchronization and manual settings, or in incorrect operation of the system services cache.
The first step to solve the problem should be to completely clear the date settings. Disable all automatic options, reboot the device, then manually set the correct parameters and only then try to enable synchronization again. If the problem persists, it may be a service failure Google Play Services.
The table below shows the main symptoms of timing problems and the probable causes of their occurrence:
| Symptom | Probable cause | Solution method |
|---|---|---|
| Time resets when you turn off the phone | The CMOS battery is dead or the software is faulty | Charge the phone, check for updates |
| The time zone does not change while roaming | The "Auto-select zone" option is disabled | Enable automatic detection |
| Time is 1-3 hours behind | Wrong city selected in settings | Manually change time zone |
| Certificate errors in the browser | Strong discrepancy between the date and the real one | Synchronize time via the network |
If none of the software methods help, you should consider resetting the settings to factory settings. This is a drastic measure that will delete all user data, but often eliminates deep system errors that affect core services. Before performing a reset, be sure to back up your contacts and photos.
Using ADB for advanced setup
For users who have superuser rights or know how to work with USB debugging, it is possible to change the time through console commands. The tool ADB (Android Debug Bridge) allows you to send commands directly to the system, bypassing the graphical interface. This can be useful if the touch screen does not work or the settings menu is blocked.
To change the time via ADB, you need to connect the phone to the computer, enable USB debugging and launch the terminal. The command to set the time requires root access or specific permissions depending on the firmware version. The command syntax may look complicated for an untrained user, so use this method only in extreme cases.
adb shell date MMDDhhmmYYYY.ssIn this command MM - month, DD - day, hh - hours, mm - minutes, YYYY —year, ss —seconds. For example, to set December 25, 2023, 14 hours 30 minutes and 00 seconds, the command would look like this: adb shell date 122514302023.00. After entering the command, the time will change instantly, but upon reboot it may return to the network value if the corresponding services are not disabled.
⚠️ Attention: Using ADB commands to change system parameters may lead to unstable operation of the device. Incorrect command format or setting an impossible date may cause cycling or application errors.
Before entering any commands through ADB, write down the current time settings on paper or take a screenshot. This will allow you to quickly restore the system in case of an error.
The influence of third-party applications and widgets
Often users think that the problem over time lies in the system, while the culprit is installed applications. Various clock widgets, alarms, and calendars may have their own time format and time zone settings that take precedence over the system ones.
For example, an alarm clock application can ignore the system time zone and use the one that was selected when it was first installed. This causes the alarm to ring at the wrong time, even if the clock on the screen shows the correct time. Check the settings of all installed timers and task schedulers.
In addition, some energy saving applications may aggressively terminate the time synchronization process in the background, considering it a waste of resources. If you use such utilities, add the system time service to the list of exceptions or whitelists to ensure correct operation.
If the time is confused only in specific applications, the problem is not in the Android system, but in the settings of the application itself or its cache. Try clearing the data of the problematic application.
Why does the time reset after turning off the phone?
This may occur due to a deep battery discharge when the voltage is not enough to maintain the real time clock (RTC) in pause. Also, the reason may be a software failure of the firmware, which does not save settings to non-volatile memory.
How to change the time on the locked screen?
You cannot directly change the time on the locked screen. You need to unlock the device, go to settings and change the system time. After this, the view on the lock screen will be updated automatically.
Does changing the time affect the operation of banking applications?
Yes, banking applications are very sensitive to time desynchronization. If the time on the phone differs from the server time by more than a few minutes, the application may not connect to the server for security reasons.
Is it possible to set the time from the future?
Technically, this is possible through manual configuration, but is highly not recommended. This will lead to errors in the operation of SSL certificates, the inability to log into most sites, and malfunctions of instant messengers and mail.
Where can I find the time settings in Android 7.1?
In Android 7.1 the path is usually the following: Settings → System → Date and time. In some shells, the "System" item may be missing, and the settings are located immediately in the main menu or in the "Advanced settings" section.
