so it seems that the ds1302 and ds1307 are both fault ridden , is there any other rtc that is reliable ?
I tested a bunch of DS1307 chips for many weeks back when the time library was created and never saw a fault. If you haven’t already, try one on well-made breakout board before ruling out this chip.
Mod – It looks like this RTC discussion is hardware related rather than anything directly to do with the time library. I think the posters issues would be apparent using any test harness for the RTC chips. If there is further discussion on RTC chips, it may be better to put this back in its own thread and add a link here to that, to keep this thread focused on the Time library .
