Yes, synchronizing to the atomic clock or using STP is an audit 
requirement for
some types of audits.  But as others have stated, adjusting a clock 
backwards is
a real problem.  My thought was to use the MF as the time server and 
sync the
server farm to the mainframe, then write a compensating control for the 
auditors
that explains just how accurate the mainframe clock is.  As someone 
else pointed
out, mainframe clocks are very, very precise, accurate to within a 
small
fraction of a second over a 10-year period.

Dear all,
We have a strange request to synchronize the mainframe time with global
internet time. However, we need to do that continuously, i.e. every 30
minutes.
