I'd argue that the most important factor is compatibility with the
rest of the OS. If the underlying OS doesn't support leap seconds,
then nor should the Haskell environment.

IOW, the Haskell functions need to be wrappers around the
corresponding libc functions (or their Windows equivalents). I.e.:

	Haskell			C

	getClockTime		gettimeofday
	toCalendarTime		localtime
	toUTCTime		gmtime
	toClockTime		mktime
