From Scott Bailey:
It takes a calculator to decode the timestamps.  But no more!
Timestamps using the attached patch are displayed as follows:
   Timestamp = MM:SS mmm absolute (UTM)
or
   Timestamp = MM:SS mmm relative
where M is minutes, S is seconds, and m is milliseconds.
This is in accord with 'IEEE Std 1278.1-1995' section 5.2.31.
