Setting and Verifying the Alarm and Time Zone
New enhancements to the PIX firewall acquiesce you acclimatize both the beheld time
zone advice and annual for aurora accumulation time.These enhancements
allow you to appearance the alarm advice in a readily barefaced time format
without accepting to catechumen the centralized UTC into your bounded time.
NOTE
The account of application UTC is that no amount area you are located, the
base time is consistently the same. You either add or decrease a cardinal of
hours from UTC to get the bounded time. This provides a constant time
across an action arrangement that spans assorted time zones.
There are three suggestions for configuring the PIX clocks beyond an
enterprise network:
Consistently affectation the “local” time area for anniversary device, based on area the
device is located.This convenance is advantageous back you accept bounded administrators
for the firewalls and they frequently administrate and adviser their
local PIX firewalls.
Set all accessories internally to the UTC architecture for a accepted alarm across
multiple time zones.We already discussed the allowances of application this
method.
Set all accessories to affectation the bounded “headquarters” time zone.This is
useful back you accept a centralized IT agents that manages firewalls across
the globe.
To analysis the time on a PIX firewall, blazon appearance clock. If you adjudge to use the
local alarm on the PIX, use this command to set the clock:
clock set
The hh:mm:ss constant is the accustomed hours:minutes:seconds in the 24-hour
format.The ages should be the aboriginal three characters of the month, again the
day application numerals 1 to 31, and after the year, from 1993 to 2035. PIX version
6.2 supports aurora accumulation time (summer-time) and time zones.
The command architecture to set the summer-time area constant is as follows:
clock summer-time
hh:mm [offset]>

Configuring System Management • Chapter 6 323
The area constant is the name of the time zone, such as PST.The other
parameters are acclimated to set the alpha and the end of summer time. If you appetite to
make this a alternating event, change the command slightly:
clock summer-time
month hh:mm [offset]>
The new constant alternating will alpha and stop the summer-time adjustment
each year at the aforementioned point. Here is an example:
PIX1# appearance clock
04:22:19.659 UTC Mon Oct 7 2002
PIX1# configure terminal
PIX1(config)# alarm summer-time pst date 7 april 2002 00:00 27 october
2002 00:00
PIX1(config)#
PIX1# appearance clock
05:23:02.890 pst Mon Oct 7 2002
PIX1# appearance alarm detail
