But if that was too fast for you, check the
United States Naval Observatory Master Clock.
Or listen to a "live" broadcast of
the USNO Master Clock Voice Announcer.
Requires RealPlayer®

Because it's buffered by the RealAudio® player,
the audio time will be delayed (late) by at least four seconds
from when it left the USNO Master Clock time.
One could also check the Network Time Protocol page.
Files in this directory or the related newsgroup comp.protocols.time.ntp are also good sources for more information. If you want to find an NTP site that is close to you, want to know about Radio Timecode-receiving Clocks, need the accuracy of a cesium-beam time source or are just curious about the calculation of time delay across the surface of the globe, this information is for you.
OTC's WWW site has information on various time setting and observing programs.
For those of you interested in Horology, (and other clock-related things) check this site or the newsgroup alt.horology.
