Depending on the type of laptop maybe the build-in RTC doesn't keep the time as it should caused i.e. by a depleted CMOS battery (note: No CMOS battery in portables though).
I would do a SMC reset on that laptop. If this doesn't help consider a NVRAM (or PRAM) reset.

Yesterday's crash in the logs:

Subject: RE: 2.4 crashing on macOS with time moving forward?
Thanks.
It happens in various scenarios, including when I'm actively working on the
computer (or it's at least not sleeping). It also happens overnight when the
computer should be sleeping. It doesn't seem to happen on resuming.
For example, here's this morning's (or late last night's) when the
laptop was
closed and sleeping:

Does this occur when resuming from suspend/hibernate? Also, we do read this
list, it just sometimes takes time to react.

As this continues to happen and the list seems uninterested, how
exactly should I report this bug?
Thanks.

Further info: this whole "time moved forward" thing had a
long discussion and eventual fix in 2.3:
https://forums.freebsd.org/threads/dovecot-time-moved-
forwards.82886/page-2
For the record, how my clock compares with a standard:
sntp time.euro.apple.com
+0.109836 +/- 0.031550 time.euro.apple.com
17.253.14.251
So, first there seems to be a bug in this somewhere since
dovecot is clearly getting wrong time info. Then this also
seems related to dovecot eventually crashing on me.

After last week's struggle with the new version
and my conf file, I got everything working. Now
however dovecot crashes on me every few hours.
The logs show a bunch of this kind of warning,
which I find mention of on the internets:

Note the very large jump dovecot claims is
happening in all of these, up to half an hour,
with a minimum of 48 seconds in this bunch. You
can see that it even does a pair of these in
rapid succession, like at 17:25:39 above, and
will do >10 within the space of an hour.
These seem eventually to be followed by a crash
("eventually" because I'm running this on my
laptop which isn't always open and running). The
crash log entries all start with something like
this:
Feb 07 16:17:53 imap(58315): Panic:
file ./time-util.h: line 40
(timeval_add_usecs): assertion failed:
(usecs >= 0)
The reports will end with one of these:
Feb 06 17:45:07 log(48089): Warning:
Killed with signal 15 (by pid=1 uid=0
code=unknown 0)
Feb 07 16:17:53 imap(58317): Fatal:
master: service(imap): child 58317
killed with signal 6 (core dumps
disabled - https://dovecot.org/
bugreport.html#coredumps)
One more detail, I usually do `sudo brew services
start dovecot` to run dovecot and this results in
the crashes. When I was testing this on Saturday,
I started it with `sudo dovecot -F` instead, so
that I would see problems in the terminal. It
went all day without crashing and I finally
stopped and restarted it with the brew method.
That's not a rigorous test, but it is suggestive.
Happy to provide more info, but I'm hoping this
is sufficient to suggest a course of action.
dovecot 2.4.0 installed via homebrew
macOS 13.6.9
