Chapter 9 Accessing and Monitoring PIX Firewall

Managing the PIX Firewall Clock

This section describes how to manage the PIX Firewall system clock and includes the following topics:

• Viewing System Time, page 9-15

• Setting the System Clock, page 9-15

• Setting Daylight Savings Time and Timezones, page 9-15

Viewing System Time

To view the current system time, enter the following command:

show clock [detail]

This command displays the system time. The detail option displays the clock source and the current

summer-time setting. PIX

Firewall Version 6.2 and higher provides milliseconds, timezone, and day.

For example:

16:52:47.823 PST Wed Feb 21 2001

Setting the System Clock

To set the system time, enter the following command:

clock set hh:mm:ss month day year

Replace hh:mm:ss with the current hours (1-24), minutes, and seconds. Replace month with the first

three characters of the current month. Replace day with the numeric date within the month (1-31), and

replace year with the four-digit year (permitted range is 1993 to 2035).

Setting Daylight Savings Time and Timezones

PIX Firewall Version 6.2 and higher also provides enhancements to the clock command to support

daylight savings (summer) time and time zones.

To configure daylight savings (summer) time, enter the following command:

clock summer-time zone recurring [week weekday month hh:mm week weekday month hh:mm

[offset]]

The summer-time keyword automatically switches to summer time (for display purposes only).

clock offset Offset of the system clock to synchronized peer.

root delay Total delay along path to root clock.

root dispersion Dispersion of root path.

peer dispersion Dispersion of synchronized peer.
