Utility meter with monthly reset resetted one hour too early

[envy]

The problem

I have a utility meter that I configured to reset monthly.

27 minutes ago of this writing (2024-03-31 23:27 CEST), it reset:

The timezone configured in my HA is set to "(GMT+01:00) Berlin".

When I render the template {{ now() }} I get 2024-03-31 23:28:13.972397+02:00

So, HA seems to be aware of the fact, that today (2024-03-31) there was a switch to daylight savings.

But somehow, the utlity meter thinks it's already 2024-04-01, that would be GMT+03:00 which is wrong, so it's observing double daylight savings?

Same issue with weekly reset.

[envy]

Funnily enough, my daily utility meter did reset correctly at midnight.

I also live in the Berlin TZ. For me the "last period" attribute also zeroed, which makes me believe it somehow reset twice.

To add to the same situation, reset early, Berlin TZ, last period zeroed; I have also noticed that the entire statistic for March is gone, but onyl for state, not change...

Same on my system : all my monthly utility meters have resetted twice, once (too early) with the correct value and a bit later with now a zero value.

I have a utility meter setup to reset at 23:05 every 1st, 11th, 21st of each month. We had summer time kicking in at midnight 30/31st of March. On March 1st the meter reset activated twice one hour apart, at 22:05 then at 23:05.

[maweki]

Which is all very strange as neither midnight nor 23:05 happens twice. The time change happens later in the night.

I've meanwhile traced the issue to the used dependency: kiorky/croniter#70

Which is all very strange as neither midnight nor 23:05 happens twice. The time change happens later in the night.

Note that my meter reset was 24 hours after the DST change (as scheduled) but it executed twice. I have two separate HA systems (for redundancy) with same meter setup and they acted the same way i.e. double reset. The setup has been running for one year without a noticeable issue.

Daylight savings ended on Sunday the 6th at 2am here (TZ: Australia/Hobart). HA shows the correct time but all my daily cycle utility meters are now resetting at 1am instead of midnight.
