Package: cron
Version: 3.0pl1-132
Severity: normal
Dear Maintainer,
* What led up to the situation?
I upgraded to Buster from stretch and noticed that my cron jobs were running at
~7:38 AM
instead of the time in my /etc/crontab. After some troubleshooting, I did
reinstall by
installing from 9.7 media followed immediately by apt full-upgrade. The problem
persisted.
I then did the same on a different system and found that the problem exists on
this
system as well (total of two out of two systems that exhibit the problem).
* What exactly did you do (or not do) that was effective (or
ineffective)?
I tried the default setting of 6:25 AM ["25 6 * * *"] and a few other times
(e.g., 1:00 AM ["0 1 * * *"]). cron seems to ignore all entries and the jobs
always
run at ~7:38 AM. date and hwclock agree on current time. /etc/timezone is
America/New_York
which is correct for me. TZ is not set anywhere that I can find.
/var/spool/cron/crontabs
is empty, so there should be no other/duplicate jobs causing confusion. Also,
the recent
shift to DST in the US did not change the behavior.
I googled, searched stackoverflow and bug reports, and posted in the forums. It
appears
that I am the only person to observe this behavior, so I feel like a stupid
user and have
been reluctant to send a report. However, I can reproduce the behavior on
different
systems from a clean install using the default configuration.
* What was the outcome of this action?
Nothing seems to resolve the problem.
* What outcome did you expect instead?
I expected the jobs in the system crontab to run at the specified time.

Hi,
when cron jobs are under /etc/cron.daily, they are launched by anacron,
if this package is installed, because anacron takes control of the file
/etc/crontab
If you are eager to have some jobs done at a precise time everyday, you
should not put them in /etc/cron.daily, but rather edit root's own
crontab file. Anacron runs jobs in a pretty asynchronous mode ;)
I am closing this bugreport. PLease feel free to reopen it if you want.
Best regards, Georges.
