Hi,
We found this very suspect behavior:
$ date --date '20180325 02:58:00'
date: invalid date `20180325 02:58:00'
but for the previous day it works...:
$ date --date '20180323 02:58:00'
Fri Mar 23 02:58:00 CET 2018
Is it a bug?
Adding -u or setting TZ seems a workaround.
Tested with version 8.28 on Ubuntu 18.04.4 LTS
and also with version 8.13 on Debian GNU/Linux 7
Thanks in advance,
Julien
