I still regret this! I should have called it TimeOffset or somesuch.

Leap second data is there too, so it should be possible to create a 
Data.Time.Clock.TAI.LeapSecondTable from it.

Also, it might be worth creating an OS-specific package that dealt with 
the filepaths for you, so for instance you could read in a 
TimeZoneSeries given a time zone name such as America/Los_Angeles.
