When booting the server the system time is usually set by default using the BIOS clock. We set the BIOS clock usually on an UTC value.

If you live in another time zone, this setting must be adjusted. Though the time of your server is always up-to-date, we recommend each customer who uses Linux the tool "ntpdate" and its use in /etc/crontab.

There should be the following entry:
00 01 * * *      root    ntpdate -s de.pool.ntp.org 1>/dev/null 2>/dev/null

for the adjustment of the time once a day at 1 a.m. (early).
