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})
I'm on a Debian Sid system:
