[amsat-bb] PC clock

[Larry Gerhardstein]

My PC's clock keeps getting off by enough to cause problems on near 
overhead passes.  I've seen it off by more than 30 seconds.  It is using 
Internet synchronization, which happens once a week.  Is there a way to 
force Windows 7 to automatically update clock more frequently than once 
per week.  Please don't tell me to monkey with the Windows Registry.  I 
know PC clocks are notoriously inaccurate, but this is ridiculous.
