The fix is trivial though (and have been applied to HEAD) --

Frederik Eaton reports: The Glorious Glasgow Haskell Compilation System,
version 6.4.3.20060816
{{{
> now <- getClockTime

0, tdMin = 0, tdSec = 0, tdPicosec = 999999999999}) now
*** Exception: Time.toClockTime: picoseconds out of range
}}}
This is clearly a bug. Simon Marlow comments: System.Time is kind-of
deprecated: the new time package is intended to supercede it, but I have
been reluctant to really deprecate System.Time because it comes from
Haskell98, and also because we don't have much experience with its
replacement.
