Hello.
I purchased an RTC power bank, which I've heard is built into the Raspberry Pi 5, and tested it. However, the clock is running slowly.
I synchronized the time with a GPS signal, saved the time, and confirmed that the time displayed on my phone (5:10 PM) matches exactly with the time displayed on the Raspberry Pi.
Approximately 40 minutes later, I turned on the Raspberry Pi and compared the time with my phone. The time is now running slowly.
-> The current time on my phone is 5:58 PM, but the Raspberry Pi's clock displays 5:56 PM, and the time difference is growing.
I'd like to know the cause. The power bank is functioning normally.
