Dimitris,
If you look at the AddColumn docs:
http://www.amibroker.com/guide/afl/afl_view.php?name=ADDCOLUMN
you will see the following example:
formatDateTime - produces date time formated according to your system settings
AddColumn( DateTime(), "Date / Time", formatDateTime );
This is (I guess) what you want.
Best regards,
Tomasz Janeczko
