Published date: 24 October 2019

Issue: I've noticed that the RealTime Clock on my M580 is starting to drift each day compared to the time I originally set it. What is the Accuracy of the RTC on the M580 CPU and how can I help to stabalize it?

The resolution of the real-time clock is 1 ms. The clock accuracy is affected by the operating temperature of the application.

You can mitigate this by connecting to an NTP server.
