Hello. This is a part of a solution, with explicit TimeZone Prelude Data.Time> :t \z s t -> utcToLocalTime z $ addUTCTime (fromIntegral s) (localTimeToUTC z t) \z s t -> utcToLocalTime z $ addUTCTime (fromIntegral s) (localTimeToUTC z t) :: Integral a => TimeZone -> a -> LocalTime -> LocalTime where the Integral arguments is in seconds, by docs regards paolino 2012/8/18 Adde Nilsson <trialcodr@gmail.com>
Hi. How do you add to or subtract from a LocalTime? I'm trying to subtract a second from a LocalTime value but the only API's I can find act only on the TimeOfDay part.
subSec :: LocalTime -> LocalTime subSec (LocalTime d t) = LocalTime d $ timeToTimeOfDay ((timeOfDayToTime t) - (secondsToDiffTime 1))
I'm obviously on the wrong track as this looks way too complex for what it's trying to achieve. Calling with '2012-08-18 00:00:00' gives '2012-08-18 -01:59:59' which isn't very helpful. How do I get to '2012-08-17 23:59:59'?
Thanks, Adde
