Dwarf - Thanks. I hadn't noticed there were two flavors of GMT in the clock setup.
I can understand Microsoft's thinking on this point, given that people worldwide are using the OS. But as a former U.S. Coast Guard officer, it runs against my grain not to have a clearly-labeled choice for "pure" (unchanging) GMT/UTC.
I might have coded this routine with one additional choice labeled something like "(GMT) Worldwide Reference," pointing to the same set of constants as "(GMT) Casablanca, Monrovia, Reykjavik."
In any event, switching to that zone solved the problem. I appreciate the help.
