I have a project that uses the MKR1000's RTC. When it starts, it obtains the time from NIST, then assumes that the RTC will maintain an accurate clock from then on (for months).
It seems that the RTC on the MKR1000 loses 1 to 2 seconds per day. Is this normal and is there anything that can be done to correct it (other than updating the time from NIST periodically)?
Thanks.
