Users of Xiaomi, Redmi and POCO smartphones often face the need to manually adjust system time, especially after traveling or resetting. Incorrect data in the system can lead to errors when messengers, banking applications and even blocking access to some sites due to mismatch of security certificates. In the MIUI or HyperOS operating system, this process is intuitive, but the menu can be hidden in non-obvious sections, especially if the interface is not fully translated.
There are several reasons why a device may be showing incorrect time, from simple battery discharge to software bugs after a firmware update. It is important to understand that automatic network synchronization is the most reliable way to keep up to date, but it requires a stable Internet connection. In this article, we will discuss in detail the algorithm for manual and automatic change of parameters, and also consider the specific configuration of the display format characteristic of Chinese versions of shells.
Before we make any changes, it's worth noting that time resets are often due to the wrong geographical region or time zone choices. If your device is showing the time a few hours apart, the problem is probably the location settings, not the clock mechanics. We'll look at all the nuances so you can quickly get the gadget in order.
The main way to set the date and time
To start the change, you need to go to the main system settings menu. On most modern Xiaomi models, this is done through the gear icon on the desktop or in the notification curtain. Once you open the menu, scroll down to the "Additional Settings" section or immediately look for the "Date and Time" item if it is in the root menu directory. In new versions of HyperOS, the logic of the arrangement of elements may have changed, so be careful.
Once you're in the right section, you'll see the "Use Network Time" switch, which is a key control that automatically pulls data from your mobile operator or Wi-Fi router. If the switch is active, manual time change will be blocked by the system. You'll need to turn off this feature to activate the fields for manual input. This is the standard procedure for protecting against random user errors.
Once the automation is disabled, the fields for year, month, day, hours and minutes will be available. Use the scrolling wheel or keyboard to set the exact values. Remember that the time format (12 or 24 hours) is also adjusted in the same window, which is especially true for those who are used to the American or European time-of-day standard.
⚠️ Note: When changing time manually, make sure you choose the right time. AM (before noon) or PM (afternoon), if you use a 12-hour format, otherwise you can set the time to 12 hours shift.
Automatic synchronization and time zone
The most common problem that Redmi Note and other series owners face is incorrect time zone. Even if the clock is the right time zone, the date can leave yesterday or tomorrow when crossing the time zone. In the date and time settings, be sure to check the Time Zone. There should be an Automatic tick here so that the device can determine your location by cell towers.
If the automatic definition is not working correctly, for example, it shows the time of a neighboring region, select "Select time zone" manually. In the list of cities, find the capital or major city of your current location. This action will force the correct shift relative to UTC (Coordinated World Time). For Russia, Ukraine, Kazakhstan and Belarus, this is critical because of the abolition or change of the rules for switching to daylight saving time in different years.
It is worth mentioning that network synchronization (NTP) is not instantaneous. Once the appropriate switch is turned on, it may take a device from a few seconds to a minute to get accurate data from the server. If the time does not change immediately, try turning on and off flight mode to restart the communication module and initiate a second request to the operator's network.
Change of time format: 12 or 24 hours
Many users prefer the 24-hour time format, as it eliminates confusion with half a day. In MIUI shells, this setting is often directly in the Date and Time menu, but in some regional firmware (especially Global and EEA), it can be moved to Region or Language and Input. Look for a switch that says "24-hour format" or "Use 12-hour format."
If you can't change the format with standard tools, you can use third-party themes. Some MIUI Themes interface skins have their own watch widgets that ignore system settings and display time in the format you want, but this is a cosmetic solution and does not affect system time in logs and applications.
For advanced users who want to change the format throughout the system, there are hidden menus. However, changing the system files of the time format can lead to incorrect display of the date in some applications, so it is recommended to adhere to the standard settings provided by the manufacturer.
💡
If you travel frequently, turn on the “Timesman over Network” and “Schedule Auto” feature in the battery menu so that the phone itself adapts to the new time zone without your involvement.
Specificity of Chinese versions of MIUI and HyperOS
Owners of devices purchased in the Chinese market (CN version) often face the lack of familiar switches in the settings menu. In Chinese firmware, the path may look different: Settings → Additional settings → Date and time. There may not be an explicit 24-hour format switch, since China has adopted its own standard, in which case the change is possible only through the installation of a Russifier or changing the region.
Changing the region is a powerful tool in the Xiaomi user’s arsenal. By going to Settings → Additional Settings → Region and choosing, for example, “India” or “UK”, you can change not only the format of the date (DD/MM/GYYYYYYYYY vs. MM/DDD/GYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
After region changes, the phone may need to reboot to apply all time and date settings, and check if the time zone has reset after this procedure, as the new region may have its own default time zone.

Why Time is Stuck: The Main Reasons
If you notice that your POCO or Xiaomi is constantly reset several years back (like 2015 or 1970) after the battery is completely drained, the problem lies in the hardware. Inside the smartphone, in addition to the main battery, there is a tiny pill battery or capacitor responsible for the internal clock running when it is turned off.
The second common cause is software conflict: Installing unofficial firmware, obtaining Root rights, or using modified cores can disrupt the system process responsible for synchronizing NTP, in which case, even with the Internet turned on, time will “go away” after each device reboot.
The third reason is the wrong job. SIM-The telephone operators transmit the time and date when registering the telephone on the network. SIM-The card is old, damaged or the tariff plan does not support the transfer of this data, the phone will rely on internal clock (rely on internal clock), which tend to drift.
| Symptoms. | Probable cause | Method of decision |
|---|---|---|
| Time is reset after the phone is turned off | The internal clock battery is discharged | Replacing a battery in a service or using auto-synchronization |
| Time is different for an hour. | Wrong time zone | Manually select a city or enable auto-definition |
| The date shows 1970 or 2015. | Failure of the BIOS/UEFI smartphone | Full reset (Hard Reset) |
| Time is always running ahead. | Application or firmware conflict | Checking installed applications, resetting to factory |
Solving synchronization problems
When the automatic time setting on Xiaomi stops working, the first thing you need to do is check the Internet connection. Without access to the network, the phone will not be able to communicate with time servers. Try switching from Wi-Fi to mobile Internet or vice versa. Sometimes providers block the ports used for the NTP protocol.
If the Internet is available but the time is not updated, try clearing the cache of the system application “Settings” or “Google Play Services” (depending on the OS version). Accumulated errors in the cache can prevent correct updating of timestamps. Go to Settings → Applications → All applications, find the desired one and click “Clear Cache”.
☑️ Checklist of time diagnostics
In extreme cases, when nothing works, you may need to completely reset your settings to factory settings, which will delete all data, but is guaranteed to eliminate software errors that affect system time.Be sure to back up important data in the Mi Cloud cloud or on your computer before doing this.
⚠️ Warning: Wipe Data will delete all photos, contacts and apps. Make sure you have an up-to-date backup before performing this operation.
Configuring widgets and third-party applications
Often users confuse system time settings with those of the desktop widgets. If the lock screen or desktop displays the time incorrectly and the curtain correctly, the problem is in the widget. Press and hold the watch widget, select Settings (if available), and check if it has its own time zone or format.
Third-party apps like Clock Sync or alarm clocks can ask for permission to change system time. If you've recently installed such programs, check their permissions. In modern versions of Android, access to time change for third-party applications is severely limited for security reasons, but older apps can behave incorrectly.
For those who need accurate atomic clocks, there are applications that synchronize directly with precise time servers, bypassing the carrier, which is useful for professionals who care about every millisecond, but for the average user, standard MIUI tools are enough.
💡
System time in Android smartphones is synchronized with priority: first the operator’s network, then Wi-Fi, and only if the network is not available – the internal clock of the device is used.
