getLeapSecondTable = do [....]
Returning a built-in table is worse than useless, as any program compiled with it will soon break.
Apparently, that's what the Perl library (libdatetime-leapsecond-perl) does. (It's the only thing I can find on my box that seems to worry about leap seconds) "break" as in "give slightly inaccurate results".
We could however check for /etc/leapseconds.txt, that might be useful. But it's not clear what the behaviour on Windows or other platforms should be.
Is /etc/leapseconds.txt a standardized file/location at all?
readLeapSecondTable :: FilePath -> IO LeapSecondTable
It would be nice if it had the ability to fetch the table over the net as well, perhaps? -k -- If I haven't seen further, it is by standing in the footprints of giants
