The situation when the wrong date or time is displayed on the smartphone screen may seem banal, but in practice it causes a whole cascade of problems in the operation of the operating system. MIUI, like any modern Android shell, ties a lot of background processes to the relevance of the system timer. Incorrect time stamps block access to sites due to security certificate errors, disrupt the work of messengers and make it impossible to log in a Google account.
Most often, users face this after replacement. SIM-In some cases, the system simply forgets the settings after the battery discharges to zero if the AutoDetection tick has been set. It is important to understand that manual adjustment is not just a cosmetic change, but a need to restore the normal logic of the software.
In this article, we will discuss in detail all ways to correct the calendar: from the standard settings menu to advanced methods through engineering menus and computer utilities. You will learn why time is lost on Xiaomi Redmi and POCO, how to bypass the locking of gray sliders and what to do if the date βfliesβ into the past immediately after the reboot.
Standard method through system settings
The most obvious and safe method of changing the timing is available to every smartphone owner. It does not require root rights or a PC connection. The interface of the MIUI and HyperOS shells is unified, so the path to settings will be identical for most models, whether it is a budget Redmi Note or flagship Xiaomi 14.
You have to open the main menu and find the gear icon. In the list that opens, look for the "Additional Settings" section or the "Date and Time" section if it's on the main list. This is where all the switches that synchronize with network time are located. NTP-server.
If the sliders are active (blue), the system itself determines how many hours there are, based on data from a cell tower or Wi-Fi. To set the values manually, you have to force the automation to be disabled, and then the input fields will be available for editing, and you can set the exact parameters.
Note the format. In some regions, the default is a 12-hour format with AM/PM, which often leads to confusion. By switching to a 24-hour format, you eliminate the risk of error in half a day.
β οΈ Note: If after turning off automatic synchronization sliders remain active or immediately turn back on, then the system is running a third-party application-synchronizer or activated the developer mode with forced time synchronization.
After making the changes, be sure to check the status bar at the top of the screen. If time is right but is off again a few minutes later, the problem may lie deeper - in the cache of system services or the conflict of profiles.
Step-by-step instruction: detailed guide
For those who prefer to follow the algorithm, we have prepared a detailed checklist of actions, following these steps will help to avoid errors, especially if the interface of your device is slightly different due to the version of Android or regional firmware.
βοΈ Algorithm for Date Change
The first step is navigation. The path can look like Settings β Additional settings β Date and time. In some versions of MIUI, this item is hidden inside the System Applications menu or is available through a search by settings (the magnifier icon at the top of the screen).
Step two is deactivation of automation. Find "Use network time" or "Auto-time" and put the switch inactive. The system can request confirmation of action, you can agree.
The third stage is manual installation. Click on the current date line. A calendar will open where you can select the year, month and date. Similarly, choose the hour and minute. Remember to check the time zone if you are not in the capital of your region.
Why is the date reset after switching off?
The final step is to check the applications, open your browser and try to load any page, and if the site opens, the security certificate is accepted by the system and the time is set correctly, and a connection error often indicates that the year or time zone is still incorrect.
Solving problems with automatic synchronization
Many users prefer not to mess with manual settings, but rather trust the network. However, the βAutodeterminationβ feature on Xiaomi smartphones sometimes works incorrectly. This may be due to the peculiarities of the operator, which transmits incorrect data about the time zone, or with a lock. NTP-server.
If you notice time lagging or rushing, try changing the timing source. The date and time menu often has a choice between "Network" and "GPS." Switching to GPS can help if you're out in open space, as satellites transmit reference atomic time.
It's also worth checking if In-Air mode is on, and in this state, the communication module is off, and the phone can't physically get data from the cell tower, so you can't automatically set the time without connecting to Wi-Fi.
Another reason for failure is the use of VPN-If you're connected to a server in another country, the system can automatically tweak the time of that region, assuming you've physically moved. VPN pre-set.
It is important to note that time synchronization is critical for two-factor authentication (2FA).If your watch runs away even for a couple of minutes, codes from Google Authenticator (Microsoft Authenticator) will be considered invalid.
Use of engineering menus and hidden settings
For advanced users who are faced with situations where standard settings are blocked or unavailable, an engineering menu is available, a powerful diagnostic tool that allows you to manage modem and radio parameters that directly affect the receipt of time stamps from the operator.
You can log into the engineering menu via the special Engineering Menu app (often hidden) or by typing code in the "caller." For most Redmi and POCO devices, code ##4636## works. If the code doesn't work, your firmware may have region limitations.
In the menu that opens, select "Phone Information" where you can see network status and SIM card settings. While a direct "Set Time" button may not be present, resetting the radio module settings (the "Turn off radio" button and then "Turn on radio") often causes the phone to re-query the current data from the tower, including the time.
Be careful when changing the parameters in this section. Incorrectly configuring the frequency bands can lead to loss of network signal. The main purpose here is to reboot the communication module to update the network. NITZ-Network Identity and Time Zone).
β οΈ Attention: The engineering menu is for developers. Don't change the values in fields you don't know what they're going to do. This can cause the communications module to run in an unstable way or the network to disappear completely.
If the standard code doesnβt work, you can try installing an app to log into the engineering menu from the Google Play store, but this will require an already running Internet connection, which can be problematic if time is down.
Change of date via computer and ADB
When the phone's interface is blocked by a time error or the sensor is not responding correctly, USB debugging comes to the rescue. The method requires a computer (Windows, macOS or Linux) and an ADB driver installed (Android Debug Bridge), a professional way to guarantee accuracy up to a second.
First, you need to activate the developer mode on the phone, and then you need to quickly click on the build number 7 times in the About menu, then in the Developer menu that appears, turn on the USB debugging option.
Connect your smartphone to your PC with a cable. On your computer, open the command line (CMD) or terminal in the folder with the ADB tools. Enter the connection check command:
adb devicesThe phone will have a request for debugging permission β confirm it. Now that the connection is established, you can force the system time to set the command. The syntax of the team requires the time in the format of GGGMDD.
adb shell date MMDDHHMMYYYY.ssFor example, to set December 25, 2026, 14 hours 30 minutes and 00 seconds, the command would look like this: adb shell date 122514302026.00. Once the command is executed, the time in the system will change instantly. This method bypasses any software locks in the interface.
π‘
Using ADB allows you to set the time even in cases where the touch screen does not work or the system interface is frozen due to a temporary conflict.
Itβs worth remembering that on some modern versions of Android with enhanced security measures, the date command may require root rights.If the command doesnβt execute, try adding a su prefix (if rights are obtained) or using graphical shells for ADB, such as QtADB.
Table of errors and ways to eliminate them
Below is a summary table that will help you quickly diagnose the cause of a failure and choose a solution method, and often the problem lies not in the date itself, but in the accompanying system settings.
| Symptoms. | Probable cause | Method of decision |
|---|---|---|
| Date reset for 2020 | RTC battery or firmware failure | Manual installation + check for updates |
| Time is 1-3 hours behind | Wrong time zone | Choose the right city in the settings |
| Sliders settings grey | Limitations of Administrator Rights | Disable the job profile or business mode |
| Certificate error in the browser | Wrong date blocks HTTPS | Immediately set the current date manually |
| Time changes when you change the SIM | NITZ Message Conflict Operator | Disable "Autodetermination" in the settings |
The gray slider line is a common occurrence on corporate smartphones or devices that have security profiles (MDMs), in which case time change may be prohibited by the organization's policies.
The table also shows that the certificate error is a direct consequence of the wrong date. SSL-If you have a 2015 certificate and the certificate is issued in 2023, the browser will consider the connection unsafe.
Additional recommendations and nuances of MIUI
The MIUI shell has its own power consumption features that can affect the accuracy of the clock, and aggressive energy saving sometimes freezes background synchronization processes to save battery life.
Check the battery settings for system services, make sure that Google Play Services and the Settings system component have a background activity restriction, No Limits, which allows the system to freely update time in the background.
π‘
If you travel frequently, turn on the Auto-Time Switch feature in your settings. SIM-This will allow the phone to automatically change the time zone when you register with another operator without your involvement.
Another nuance is the dual calendar, where Chinese firmware often has a lunar calendar that can visually shift the dates in widgets, which is not a mistake, but a localization feature, and you can switch the view from the desktop widget settings.
If nothing helps and time keeps flying away, consider resetting your settings to factory settings, and make sure to back up your important data to the Xiaomi Cloud or your computer before doing so.
β οΈ Warning: Resetting to factory settings will remove all personal data, photos and contacts from the internal drive. Use this method only if other methods have not worked, and be sure to make a backup.
Remember that software time glitches can be a precursor to more serious motherboard problems, such as memory degradation or plume contact disruption, especially if the phone has recently fallen.
