[time-nuts] Entering Altitude for Thunderbolt

When manually entering coordinates to the Tbolt, using either Tboltmon 
or Lady Heather, is the altitude value to be entered as MSL or as GPS? 
The Trimble docs don't seem to indicate which value is used.

Based on the surveys I've done with the Motorola receivers, at my 
location there appears to be about 30 meters difference between the two.
