I have been playing around with the RTC on the data logging shield v1 using the RTClib library trying to make it able to adjust the time with in a menu on a 20x4 lcd I have found that changing RTC.adjust(DateTime(__DATE__, __TIME__)) with this RTC.adjust(DateTime("Jan 21 2013", "05:05:05") works but I cant find a way to change out whats in the quotes for anything that I can add or subtract from.
If someone has any ideas, hits, tips, or code they could share it would be much appreciated
