    Bug 774237 - FTBFS under some timezones (eg. GMT-14)
    
    Fix the neutral offset calculations so that the fixed UTC time doesn't
    change the date in the timezones near the international date line. Divide
    offset by 60 instead of 3600 so that the Chatham Islands (GMT-12:45 with DST)
    use 9:59 instead of 10:59 like the rest of NZ (GMT-12).
