Hello -

After experiencing our first daylight time change with a production 
Epics system, we experimented with the master/slave IOC 
synchronization.

Things work fine when the master is up first, but if it is down the 
slave IOCs do NOT go to the Unix boot server to get timestamps and 
the timestamps are, to say the least, strange. Stephanie's comment is 
that a glance at the code shows why the slave IOCs to Unix boot 
server stuff doesn't work.

We have no need to tightly synchronize IOCs, and will stay away from 
the master/slave setup; this note is just a "heads up" that an 
advertised feature seems not to work.
