VERSION HISTORY

2017/01/27 - v. 1.2.7: added support for ATmega32U4 (thanks to Esteban Torre and piluex)
2016/05/21 - v. 1.2.6: fixed timestamp functions when we are in leap years (I hope definitely..)
2016/02/21 - v. 1.2.5: fixed a bug into the deltaT arithmetics that leads to double count the computation.
2016/02/14 - v. 1.2.4: updated to use with latest Arduino IDE branches (>=1.6.7)

The library uses the Timer 2, so keep it in mind if you think to use PWM on phisical pins 20 & 21.

The library uses the Timer 3 on this chip.

The library supports, due to rounding issues, only the following speed clocks:
- Atmega644/1284, Atmega48/88/168/328, Atmega8, Atmega640/1280/1281/2560/2561: 1, 4, 8, and 16 MHz
- Attiny25/45/85, Attiny24/44/84, Attiny2313: 1, 8, and 16 MHz
- Atmega32U4: only 16 MHz

Ottima libreria !
E' possibile avanzare una richiesta di aggiungere una funzione che si leghi più semplicemente ad un server NTP per sincronizzare l' ora del swRTC senza utilizzare il Timestrap tipo "rtc.UpdateClockWithNTP(timeClient.getFormattedTime()); " in modo che possa collaborare quasi in modo nativo con la libreria NTPClient ?
Grazie mille

Esistono altre librerie per la gestione del tempo via NTP, e non è nelle idee iniziali di swRTC l'intento di collegarsi in remoto per prendere l'orario. Grazie comunque del suggerimento.
