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.
