Data.HodaTime.LocalTime

An LocalTime represents a time of day, with no reference to a particular calendar, time zone or date. This module contains constructors and functions for working with LocalTime.

Normalization

A clock time can be from 00:00:00.000 to 23:59:59.99.. Adding 1 minute to 23:59:00 will cause it to roll over to 00:00:00.

Instances

Eq LocalTime

Methods

(==) :: LocalTime -> LocalTime -> Bool

(/=) :: LocalTime -> LocalTime -> Bool

Ord LocalTime

Methods

compare :: LocalTime -> LocalTime -> Ordering

(<) :: LocalTime -> LocalTime -> Bool

(<=) :: LocalTime -> LocalTime -> Bool

(>) :: LocalTime -> LocalTime -> Bool

(>=) :: LocalTime -> LocalTime -> Bool

max :: LocalTime -> LocalTime -> LocalTime

min :: LocalTime -> LocalTime -> LocalTime

Show LocalTime

Methods

showsPrec :: Int -> LocalTime -> ShowS

show :: LocalTime -> String

HasLocalTime LocalTime

Methods

hour :: Functor f => (Hour -> f Hour) -> LocalTime -> f LocalTime

minute :: Functor f => (Minute -> f Minute) -> LocalTime -> f LocalTime

second :: Functor f => (Second -> f Second) -> LocalTime -> f LocalTime

nanosecond :: Functor f => (Nanosecond -> f Nanosecond) -> LocalTime -> f LocalTime

class HasLocalTime lt where

Minimal complete definition

hour, minute, second, nanosecond

Methods

hour :: Functor f => (Hour -> f Hour) -> lt -> f lt

Lens for the hour component of the LocalTime

minute :: Functor f => (Minute -> f Minute) -> lt -> f lt

Lens for the minute component of the LocalTime

second :: Functor f => (Second -> f Second) -> lt -> f lt

Lens for the second component of the LocalTime

nanosecond :: Functor f => (Nanosecond -> f Nanosecond) -> lt -> f lt

Lens for the nanoseconds component of the LocalTime. NOTE: no effort is made to detect nano overflow. They will simply roll over on overflow without affecting the rest of the time.
