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.
