Basic Time conversion compatibility.
This module aims to help conversion between the types from the package time to the package hourglass.
Example of use (extracted from file ExampleTimeCompat.hs):
import Data.Hourglass as H import Data.Hourglass.Compat as C import Data.Time as T transpose :: T.ZonedTime -> H.LocalTime H.DateTime transpose oldTime = H.localTime offsetTime (H.DateTime newDate timeofday) where newDate :: H.Date newDate = C.dateFromTAIEpoch $ T.toModifiedJulianDay $ T.localDay $ T.zonedTimeToLocalTime oldTime timeofday :: H.TimeOfDay timeofday = C.diffTimeToTimeOfDay $ T.timeOfDayToTime $ T.localTimeOfDay $ T.zonedTimeToLocalTime oldTime offsetTime = H.TimezoneOffset $ fromIntegral $ T.timeZoneMinutes $ T.zonedTimeZone oldTime
Synopsis
- dateFromPOSIXEpoch :: Integer -> Date
- dateFromTAIEpoch :: Integer -> Date
- diffTimeToTimeOfDay :: Real t => t -> TimeOfDay
Documentation
Convert an integer which represent the Number of days (To/From) POSIX Epoch to a Date (POSIX Epoch is 1970-01-01).
Convert an integer which represents the Number of days (To/From) TAI Epoch This function allows use of the package time to easily convert the Day into the Hourglass Date representation (TAI Epoch is 1858-11-17).
This function allows user to easily convert a Data.Time.Calendar.Day into Date
import qualified Data.Time.Calendar as T timeDay :: T.Day dateFromTAIEpoch $ T.toModifiedJulianDay timeDay
Convert of differential of time of a day. (it convers a Data.Time.Clock.DiffTime into a TimeOfDay)
Example with DiffTime type from time:
import qualified Data.Time.Clock as T difftime :: T.DiffTime diffTimeToTimeOfDay difftime
Example with the TimeOfDay type from time:
import qualified Data.Time.Clock as T timeofday :: T.TimeOfDay diffTimeToTimeOfDay $ T.timeOfDayToTime timeofday
