Hello! I humbly present my contribution to the NTPClient library.
I've tried not to change much of the way the library works and aimed to improve on it instead.
Here are the changes that I made:
Added processing of fractional time in forceUpdate() to allow syncing to the exact NTP time.
Added sanity checking of received timestamp before using it.
Added millis() rollover protection in getEpochTime().
Added new function, setEpochTime(), to set NTPClient's internal currentEpoch from hardware RTC time.
Changed the default updateInterval to 1 hour.
Added 'Advanced_with_RTC' example to demonstrate new capabilities and accuracy.
Sincerely,
afdp777
