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.

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:
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, ctMin = 0, ctSec = 0, ctPicosec = 0, ctWDay = Thursday, ctYDay = 1, ctTZName = "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, ctMin = 0, ctSec = 0, ctPicosec = 0, ctWDay = Thursday, ctYDay = 1, ctTZName = "UTC", ctTZ = 0, ctIsDST = False})
