On one LAN-synced system it took bout 90 minutes to get to within its 
normal offset range, and about the same on a Windows-XP system with a GPS 
reference clock.  On the Windows-7 system, with a GPS ref-clock, it took 
about 5 hours.

I do wish there were some way of speeding this up - a variable loop 
bandwidth or something like that.
