Thanks a lot for the patch! The transition at Friday/Saturday definitely feels a little weird for Iran, but I found a couple of other newspaper clips and they all say "hour 24 of Friday" which most probably means Friday/Saturday.

I hunted down the exact time of Iran's transition from +0400 to +0330.
Thanks for doing that. I installed the attached proposed patch to the development repository.
It appears that the 1978-11-10 change from +04 to +0330 was at midnight between Friday and Saturday, whereas the 1977-10-20 change from +0430 to +04 was at midnight between Thursday and Friday. Historically, both Thursday/Friday and Friday/Saturday transitions have been reported in nearby countries (e.g., Jordan) so they're both plausible here.
