There are differing states.  My pair went OK+Standby in about 10 minutes
but they're not "stable" at that point.

Here's a log snippet:

Log 019:20141128.00:00:00:  Power on
Log 020:20141128.00:00:26:  Power settings ok, Int: 17 dBm, Ext: 17 dBm
Log 021:20141128.00:52:21:  Position hold mode started
Log 022:20141128.01:28:32:  GPS reference valid at 20141128.20:34:00
Log 023:20141128.20:35:04:  Locked mode entered
Log 024:20141129.10:35:03:  Ready for 4 hour flywheel
Log 025:20141129.16:35:03:  Ready for 8 hour flywheel

The first timestamp after power-on is 00:00 of the last valid date prior to
power-off.  I assume the deltas are correct.  So 1:29 to Locked and 20 more
hours to "stable".  Holdover uncertainty continues to decrease for many
more hours.  It decreased from hundreds of microseconds to 3 at the time of
that log and is now at  900 nanoseconds.
