Will SNTP adjust the TOD clock to the possibly more accurate time elsewhere in the enterprise, or merely adjust the remainder of the enterprise to the incorrect time of the mainframe?

It's pretty hard to rebut the argument, "Why shouldn't the mainframe adjust itself to the correct time elsewhere in of the enterprise rather than demanding that the remainder of the enterprise adjust to the mainframe's incorrect time?" with a blunt "It can't."
