Dates are very important for a Timestamping Server. Though we define the preferred date-format as:
0000-00-00 00:00:00 yyyy-mm-dd hh:mm:ss date: y = year m = month d = day time: h = hour m = minute s = second
Only internally, where required by SQL or Database-Restrictions, we will convert dates accordingly.
If we do so, we are ISO 8601 compliant: http://www.esperanto.uklinux.net/iso8601/iso8601.php
