UCD timestamps only work for 15 Hz configurations

Description

The timestamps for clock events are sporadic when the rep rate isn't 15 Hz. At CMTF, for instance, the rep rate is 20 Hz and the timestamps for the $8F event never have a 0 microsecond value (except by accident.) Try to understand why this is occurring.

While looking a different problem, I noticed the $02 timestamps followed a pattern (instead of changing once every 5 seconds):
