Dateformat %H doesn't work

[Forza-tng]

I am using logrotate-3.21.0 on Gentoo Linux AMD64.

The problem i am experiencing is that the hour is always 12, no matter when logrotate runs. This is evident if we look at the timestamps from ls:

-rw------- 1 root root 40320853 Oct 18 14:02 bees.3t_backup.log
-rw------- 1 root root  3587829 Oct 17 21:06 bees.3t_backup.log-20231016-120700.zst
-rw------- 1 root root  2901724 Oct 18 07:01 bees.3t_backup.log-20231017-120111.zst
-rw------- 1 root root  6894067 Oct 18 13:00 bees.3t_backup.log-20231017-120112.zst
-rw------- 1 root root  4650221 Oct 18 03:01 bees.3t_backup.log-20231017-120123.zst
-rw------- 1 root root  3872284 Oct 18 00:33 bees.3t_backup.log-20231017-123328.zst

My logrotate.conf:

create
minsize 1M
maxsize 100M
notifempty
maxage 30
rotate -1
dateext
dateyesterday
dateformat -%Y%m%d-%H%M%S
compress
compresscmd /usr/bin/zstd
uncompresscmd /usr/bin/unzstd
compressext .zst
compressoptions --long --ultra -15 -T4
nomail

include /etc/logrotate.d

/etc/logrotate.d/bees

/var/log/bees/*.log {
    copytruncate
    notifempty
    missingok
}

Logrotate is run via /etc/cron.hourly/logrotate

#!/bin/sh
echo `date` >> /var/log/logrotate.log
/usr/bin/logrotate /etc/logrotate.conf >> /var/log/logrotate.log 2>&1
EXITVALUE=$?
if [ $EXITVALUE != 0 ]; then
    /usr/bin/logger -t logrotate "ALERT exited abnormally with [$EXITVALUE]"
fi
echo `date` >> /var/log/logrotate.log
exit $EXITVALUE

Since you rotate hourly, you shouldn't use dateyesterday but datehourago.

Otherwise #554 removes the hardcoded noon time.

Thank you. I removed dateyesterday and it works. I see why the hour was set to 12.

I don't actually want to rotate every hour, but sometimes certain logs grow quickly and I want to rotate them early (max size).

After reading the dst issue, I decided to set TZ=UTC-0 which should not use DST. Am I right in thinking this?
