Whether I try to sync with my PC clock or try to update with a fixed date and time, the date is right but the time is always wrong. Any suggestions?

Thanks!

If you are synching via the example code, the time is the start of compile time. So there will always be a lag equal to the combined compile/upload and boot times before the RTC gets set.
