Thanks for the bug report. > 1. The report specifies that the field ctSec of datatype > CalendarTime must be exported outside the module. In Hugs, this field > is missing from the exports list. This is already fixed in the development version, which uses the same Time module as GHC. > 2. The report requires (see the end of the penultimate paragraph > before the library starts) that " toClockTime l converts l [...] > ignoring the contents of the ctWDay , ctYDay , ctTZName , and > ctIsDST fields". Hugs, however, does not ignore ctIsDST . It is wierd: it constructs an argument using ctIsDST, and then the primitive evaluates that argument but ignores its value. I'll remove the argument from the primitive. > 3. Additionally, the behaviour of the function diffClockTime is > strange in Hugs.

There seem to be problems with dates before year 1970. That sounds like a Posix problem. _______________________________________________ Hugs-Bugs mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/hugs-bugs
