Thanks for catching that mistake. I see that I transcribed Mok Ly Yng's 2003 web page incorrectly; it says the transition occurred at 4 o'clock (16:00) UTC, which agrees with your 23:30 local time. I installed the attached proposed patch. I found confirmation of this correction on page 1 of the Straits Times, 31 December 1981, in an article headlined "Tonight's revelry will end half-hour earlier".
