I've been staring my eyes out trying to find a function that converts a string into a ClockTime or CalendarTime. Basically something like C's strptime(3). I can't seem to find anything like it in System.Time, there are function that convert _to_ a string, but nothing that converts _from_ a string it seems. Where should I look? /M -- Magnus Therning (OpenPGP: 0xAB4DFBA4) magnus@therning.org Jabber: magnus.therning@gmail.com http://therning.org/magnus Software is not manufactured, it is something you write and publish.

The MissingH.Time.ParseDate [1] module might be what you want. There's also one from Bjorn Bringert [2]. I haven't used either though, so I can't recommend anything between them. Cheers, D.

Those two are the same code. I have a preliminary new version which can also parse most of the types from the time package (Data.Time.*) available at: http://www.cs.chalmers.se/~bringert/darcs/parsedate-2/ /Björn

Hi Magnus, thanks for the bug report. I have fixed this now in the version of the library available from http://www.cs.chalmers.se/~bringert/darcs/parsedate/ I intend to retire that version, and instead switch to the new implementation available at http://www.cs.chalmers.se/~bringert/darcs/parsedate-2/ This supports both CalendarTime and the new much nicer Data.Time types. However, the implementation is still incomplete (about as complete as the old version I think). It is missing support for week date formats and the like, and there is no test suite or QuickCheck properties (and thus there are surely lots of bugs). By the way, if you want to be sure that I see your bug reports about any of the libraries I maintain, please to cc the reports to me, or send them to me directly. /Björn

Not quite what you want, but: "read"? (opposite of "show") Regards, Malcolm
