Alarm triggering prematurely for certain times

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?

Start with the `thisRTC.alarm1 = (time.gmtime(newAlarm), "monthly")` assignment and trace the DS3231 alarm1 handling for the `monthly` and `weekly` modes. Reproduce the case where the alarm is set exactly one hour ahead, then verify that updating it does not trigger immediately and still works for the reported future times.
