No, you use the setTime method. Lets say you want to set it to 11:30, then you'd do something like this...
//setTime(byte sec, byte minute, byte hour)
rtc.setTime(00, 30, 11)
I dont think it's as simple as that. It looks like I need to set some sort of pointer to each of the variables "hour", "min","sec".
I found this in the library
setTime(byte sec, byte minute, byte hour)
which I believe is
rtc.setTime(00, 30, 11)
So I think I need to interact with/point to, the "byte sec, byte minute, byte hour". If i can manipulate those at the byte level I think it might work?
