It doesn't even have to be a full-hour shift. Some countries use timezones with offsets given in 15-minute resolution, so any software used globally already has to support 15-minute shifts. Adding support for 1-minute shifts in timezones might be easier than Y2K. I guess a bigger issue with existing software, if for some reason it couldn't be updated anymore, would be the maximum offset that can be accepted or represented. There might be a sanity check requiring the offset to be smaller than 24 hours as the current maximum is 14 hours. The ISO 8601 format has only two digits for hours in the UTC offset, so that wouldn't work for longer than a million years. -- Miroslav Lichvar _______________________________________________ LEAPSECS mailing list LEAPSECS@leapsecond.com https://pairlist6.pair.net/mailman/listinfo/leapsecs
