- Timezone offsets are in minutes (apparently this is necessary - if someone could provide a reference I'd be grateful). It's just occurred to me that since TAI is a valid timezone name, it isn't always sensible to ask what the "timezone offset" is.
http://www.timeanddate.com/time/abbreviations.html lists several timezones with half-hour offsets (e.g., Newfoundland).
Should there also be a function to get offsets (in seconds) between UTC and TAI?
yes. this would solve another problem I mentioned in a different email about the user implementing their own time types and needing the raw leap second info. perhaps: leapSeconds :: ClockTime -> Int returning the number of leap seconds before the given time. or even better getLeapSeconds :: [ClockTime] just a (possibly infinite) list of known leap seconds. I say possibly infininte since some implementations might want to heuristically predict future leap seconds.
