a minute is not a minute

Hi,

I've got an Honor Magic5 Pro with Android 15 and Magic OS 9.

I needed a timer which beeps every 5 minutes. (I have to wait until the time is 10 am, 10:05am, 10:10am, 10:15am .... to strat the timer)

The 5 minute timer gets repeated 100 times. After 15 minutes I found out that the time in the app is faster than the android time. After 15 minutes later the gap is bigger and gets bigger over time.

I don't know how the time is getting calculated, but there is a different between the app and android time.
