Configuring the date and time on PIX OS 6.3

Summertime again.
All of my servers are synced with a central NTP and pick up summertime nicely.
Except my Cisco PIX 515e.
Turned out that I didn’t configure my date time settings very well.
So, as well for my reference as for your information:


clock timezone CET 01
clock summer-time CET recurring last Sunday March 2:00 last Sunday october 2:00
ntp server i.p.a.dr source interface
ntp server i.p.a.dr source interface


The clock timezone command is tricky…You have to specify your own timezone AND the offset against UTC.
A list of timezone abbr. which Cisco uses can be found here.
