To set time:

$ sudo /usr/sbin/ntpdate pool.ntp.org
29 Sep 23:48:31 ntpdate[9404]: adjust time server 66.250.45.2 offset
0.001289 sec

To date info about your timezone settings:

$ zdump /etc/localtime 
/etc/localtime  Sat Sep 29 23:49:19 2007 EDT

Options:

$ ls /usr/shaoneinfo/ | egrep -v "^d"
total 78
-rw-r--r--   1 root  wheel    755 Aug 22 11:11 CET
-rw-r--r--   1 root  wheel    837 Aug 22 11:11 CST6CDT
-rw-r--r--   1 root  wheel    679 Aug 22 11:11 EET
-rw-r--r--   1 root  wheel     56 Aug 22 11:11 EST
-rw-r--r--   1 root  wheel    837 Aug 22 11:11 EST5EDT
[...]

To set timezone:

$ ln -s /share/zoneinfo/$WHATEVER /etc/localtime

For you probably PST8PDT.

For your best NTP experience, use OpenNTP from
ports: /usr/ports/net/openntpd/
