Have there actually been any time zones that are not an even multiple of a whole minute since the advent of leap seconds? The only non whole minute time zone I know about is Dublin Mean Time, which hasn't been used since 1916. On Feb 15, 2015 3:48 PM, "John Haxby" <john.haxby@oracle.com> wrote:

Also, general question: is there any standard on how leap seconds are to be handled in timezones that have an offset that is not a multiple of one whole minute? What does tzcode do now?
Leap seconds are inserted or deleted at midnight UTC at the end of March, June, September or December with at least three months notice. So a leap second could be inserted or deleted at about lunchtime in New Zealand or 5.30am in India.
