¶ Q：How to synchronize time?
1. Android devices:
In Android devices, the time synchronization function is turned on by default, so no settings are required.
If you suspect there is an error in the time, you can go to "Settings" -> "System and Updates" -> "Date and Time" → "Automatically set time" option and then turn it on again for synchronization.
2.iPhone or iPad:
Please make sure you have the latest version of iOS or iPadOS installed. Enable "Automatically set" in "Settings" -> "General" -> "Date and Time", and the system will automatically set the date and time according to your time zone. If you suspect there is an error in the time, please turn off the option and turn it on again to synchronize.
3.Windows PC：
Right-click on the time at the bottom right, select "Adjust Date/Time", click and select "Sync Now" to complete the synchronization.
4.Mac ：
Select "Apple" menu -> "System Settings" -> "General" -> "Date and Time". If "Automatically set date and time" is enabled, turn it off and on again to sync.
