RTC with 1ms resolution - YYYY-MM-DD HH:MM:SS.mmm

Hi!

I would like to create a RTC for stamping log messages, with 1ms resolution and including time from year to millisecond, like: YYYY-MM-DD HH:MM:SS.mmm.

What would be the best solution?

The 32kHz clock is not divisible by 1000, which means that some special handling is needed for accurate results.

regards, Elm
