Re: [Haskell-cafe] string to date?
Quoth Magnus Therning, nevermore, 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? 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.

I noticed one thing when playing around with ParseDate.parseCalendarTime
in ghci:
parseCalendarTime System.Locale.defaultTimeLocale %Y 2006
Just (CalendarTime {ctYear = 2006, ctMonth = January, ctDay = 1, ctHour = 0,

UTC, ctTZ = 0, ctIsDST = False})
parseCalendarTime System.Locale.defaultTimeLocale %Y%m%d 20061109
Nothing
parseCalendarTime System.Locale.defaultTimeLocale %C%y%m%d 20061109
Just (CalendarTime {ctYear = 2006, ctMonth = November, ctDay = 9, ctHour = 0,

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.
