I noticed today that my windows machine at work--the one that is constant on--had a clock that was off by about 2 minutes. This was odd in that I knew I had enabled "Internet Time" (no, not that silly thing Swatch came up with)--the Microsoft name for the network time protocol (NTP).
Apparently the default is to check every 7 days. I suppose with the median of computer users, that's Good Enough (tm), but I like to know what time it is (does anyone really care?). It is also annoying when my laptop (linux) and my desktop are showing different times. A little searching and I found the appropriate registry key to change so that I can set it to something more sane for this computer.
WARNING: Unless you know what you are doing, don't mess with your registry. yadda yadda yadda.
Here's the key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\
TimeProviders\NtpClient
Value: SpecialPollInterval
Type: REG_DWORD (DWORD Value)
Data: Seconds
Now back to your regularly scheduled emptiness.
