    Re: half-hour time zones

    Dan:
    
    Actually, it was weirder before:    I lived in Kathmandu from 1972-1976.   The
    time offset from GMT was then + 5 hours and 40 minutes, not 30 minutes.  India
    was and still is +5h 30m and that would never do for Nepal!   I believe it
    remained so for a number of years until, perhaps, 1986.   Now, most sources say
    it's +5h 45m.   Go figure :-)
