In a CMS environment you're talking about "personal time zone" support so that the guest could change its own tz offset and names. The DST changes would still occur, managed by CP. And as you suggest, CMS could move to handling time entirely on his own without the help of CP. > > f) An absolute TOD clock value that is expressed in LOCAL TIME. > > > ??? Isn't IBM's recommendation that TOD clock run on UTC? Yes, but that has nothing to do with how application express time values. Point is, if you want to express local time (without knowing what the offset is), you just tell the OS that you're using local time values.
