Question on Clocks

Postby mattganis » Tue Dec 06, 2011 11:43 am

I'm not sure if this is the correct forum or not, but it is clock related ;-)
(if I'm posting in the wrong place, please let me know where I should post this)

I'd like to set the date/time on my Arduino (without a RTC shield or Breakout board) - is that possible ?

I included Time.h and did a: setTime(00,00,0,11,28,11);

Which I thought would set the time to November 28, 2011 at 00:00:00

but when I reference month(), day() or year() I get some odd results (for example reporting that it's July 31, 2014 (not 2011).

am I doing something wrong ? do I have to have a RTC to do this ?

Thanks....Matt Ganis.

If you download RTCLib, there is a "softRTC" example that uses the internal Arduino timer.
