Sometimes Macs, especially laptops, don't keep very good time. I've
observed time offsets over 15 minutes on some Macs using Apple's defaults.
The problem is the "interesting" choices Apple made for NTP parameters.
Apple hides NTP behind "Date & Time" System Preferences.
See this KB article for some of the details:
Mac OS X 10.4: Network Time clients lose synchronization
http://docs.info.apple.com/article.html?artnum=303731
This article still mostly applies to 10.5.
I always customize ntp.conf files, and cross my fingers that a future
Software Update won't clobber them. My Macs stay within a few milliseconds
of true time.
For more than you ever wanted to know about NTP: http://www.ntp.org

I am comparing it to

and
<http://tycho.usno.navy.mil/cgi-bin/timer.pl>http://tycho.usno.navy.mil/cgi-bin/timer.pl
yes, my mac's location and timezone are correctly set...
