  When you say "crystals used to control the timing in computers",
are you referring to the parts that make up my actual FreeBSD
Server (ie: Motherboard)?  Or Parts in the GPS Device (ie: Sure Elec.
Or in the Satellites receiving the GPS signal?

 I'm just trying to gauge, what hardware should be looking to obtain
improve that frequency offset. Or is it a moot point unless I'm going
invest in some high dollar atomic clock?

 Or better yet, can I buy quality crystals from DigiKey and do some
soldering in whatever devices that need crystal upgrading?
