Forbes.com: Your Own Digital Master Clock

Forbes.com: Your Own Digital Master Clock: "The latest version of Microsoft's (nasdaq: MSFT - news - people ) Windows and Apple Computer's (nasdaq: AAPL - news - people ) OS both have a 'date and time' settings control panel that lets you synchronize your computer's internal clock with time servers. Both run their own time servers: Apple's has an address of time.apple.com, while Microsoft's is at time.microsoft.com. You also have the option of selecting the time server of your choice, including those run by the chief time keepers of the U.S., the National Institute of Standards and Time or the U.S. Naval Observatory."

SAD: A nice feature that I probably should have known, but didn't, was built into Windows XP. I was doing a search on what time sync software I wanted to install on my system (for purposes of digitally recording material based on time) and, voila, something else the OS takes care of automatically.
