Windows Vista and newer:
- w32tm /query /status
- w32tm /config /manualpeerlist:”0.pool.ntp.org 1.pool.ntp.org” /syncfromflags:MANUAL
- net stop w32time
- net start w32time
- w32tm /resync /force
Windows 2000: w2k, you should set up a sntp server so that your computer clock automatically synchronizes with a time server: net time /setsntp:{Server Address}
Windows XP has a nice select box to use to enter this information in the set-time window.
A free NTP Server provided by the USNO for the Pacific Time Zone:
tick.ucla.edu
A much more reliable (because it's distributed over 500 servers) is:
pool.ntp.org
Some firewalls, including many SOHO ones that I have run into block NTP. I suspect they internally capture those packets to do time synchronization of their internal clock. So... you can use a HTTP based "daytime" protocol time tool to get a good enough time sync.
NIST supplies a NISTIME-32bit client here: http://www.nist.gov/pml/div688/grp40/its.cfm
A cross platform client (I haven't tried yet) - Open Source - it looks like it's more command line (scriptable) friendly: http://utime.sourceforge.net/
