For zBX purposes, the need for common time is to get logs properly 
sequenced.  It doesn't have to be ultra-accurate, just "close enough".  By 
resyncing the BOC every hour, that becomes doable.

If you want your apps to all have a common time reference, then run STP on 
the z side and an NTP client on each non-z OS image.

Will there be alternatives to that in the future?  Dunno.
