The "Asia/Jerusalem" weirdness is because Daylight Savings Time is a big church-and-state issue. Religious people want the workday to be convenient for holidays that start at sunset.
This led to decades (up to the mid-'00s) where Daylight Savings was the result of annual negotiations between religious and secular parties. It often caused problems when the decision wasn't made until juuuust before the transition date.
There are still exceptions built in to prevent Daylight Savings from ending on Rosh HaShanah, so that's probably the future stuff.
