Well I have. The attached module (TimeExts, based on Time)
is supposed to provide ways of adding
and subtracting times in a general way. There is also a test program,
TestTimeExts.hs. Unfortunately there are two
problems:
(1) the test program is mysteriously deadlocking, giving the result:
Start and NowMon Dec 31 10:43:55 UTC 1973

Whole Picos

Whole Seconds
Fri Dec 3 09:12:34 UTC 1999
Whole Minutes
tte: fatal error: No threads to run! Deadlock?
I say "mysteriously" because I am not using concurrency at all,
so I suspect GHC is to blame;
(2) with this e-mail I go on holiday until Tuesday week.
So I suggest that the GHC people find out why I am getting a deadlock
and fix it, then maybe I'll be able to sort it out when I get back.
Or alternatively anyoone else is welcome to fix my code if they feel
up to the challenge. I know the bit that ought to be trickiest - the
Gregorian Calendar code - works, because I have checked it out fairly
thoroughly with Hugs.
