Have we not learned, yet, the "don't lie to the computers" rule? How *would* the timezone libraries handle "DST always on"? They would still have to flap, twice a year, right?
It depends. The easy ones have two settings with an optional third. 1. Offset from UTC 2. DST yes/no 3. Specify date and time to switch DST on/off. Setting 3's default was tweaked in 2007 in the US when DST was expanded.Easy-peasy. Set the appropriate offset in option 1 and set option 2 to No. Option 3 is irrelevant.
Some systems are dumbed-down with drop-down menus listing cities like "Americas-Los Angeles" and similar. These will require a bit of work on the back end.
