I'm using the DS3231 alarm 1 as a watchdog by attaching it to the reset pin of my Jetson NX. The python script running on the Jetson constantly updates the alarm time to be some time in the future. This has worked fine when setting that alarm to ~30min in the future while looping every 10min, but it seems like if I set that alarm time to be exactly 1hr from now, the alarm triggers prematurely the moment that I set that new alarm to +1hr from now.
My line of python used to set the alarm looks like: thisRTC.alarm1 = (time.gmtime(newAlarm), "monthly")
where newAlarm is an epoch time in seconds +1hr from now.
I've tried "monthly" and "weekly".
What's going on here? Why does the alarm trigger as soon as I set it for that particular time?
