As part as a hobby project I built a relatively simple BCD binary LED clock using a PIC micro controller and a DS1307 RTC. Upon battery power loss the DS1307 resets back to 01/01/00 00:00:00 which makes sense. However, since the user is only able to see hours, minutes and seconds on my clock it makes no sense to set the date.
My question is, what is the relevance of setting the date in a DS1307 in relation to timekeeping. As far as i know the only relationship between time and date is a leap second correction every few years which i doubt the DS1307 implements.
Is it okay to let the date remain 01/01/00? I would assume it wouldn't make the time drift a lot but maybe i am missing something.
Either way, it's just a hobby clock, accuracy isn't mission critical, I'm merely asking out of curiosity.
Thanks in advance!
