Dear all,
I have found that my RTC (M41T00) is capable to make precise
compensation of offset in the Control register.
Its driver, rtc-ds1307.c has support for such offset compensation and
provide the /sys/class/rtc/rtc0/offset file.
Compensation tested and operate as expected, when I manually read/write
offset value (in PPB) from/into the /sys/class/rtc/rtc0/offset file.
Does handling of such RTC offset already automatized somehow instead of
doing this manually?
I ask for community, because do not want to invent another one wheel if
there are something already implemented for such purpose.
Best wishes.
