Data.HodaTime.TimeZone

Description

This module deals with loading TimeZone information with which to construct ZonedDateTimes.

Synopsis

Types

data TimeZone Source #

Represents a time zone. A TimeZone can be used to instanciate a ZoneDateTime from either and Instant or a CalendarDateTime

Instances

Instances details
Show TimeZone Source #

Shows a TimeZone by its identity only (the transition maps are a derived cache, not part of identity).

Instance details

Defined in Data.HodaTime.TimeZone.Internal

Methods

showsPrec :: Int -> TimeZone -> ShowS #

show :: TimeZone -> String #

showList :: [TimeZone] -> ShowS #

Eq TimeZone Source #

Two TimeZones are equal when they denote the same zone (compared by identifier). The transition maps are a derived lookup cache fully determined by the identifier, so they are not part of the zone's identity.

Instance details

Defined in Data.HodaTime.TimeZone.Internal

Methods

(==) :: TimeZone -> TimeZone -> Bool #

(/=) :: TimeZone -> TimeZone -> Bool #

Hashable TimeZone Source #

Methods

hashWithSalt :: Int -> TimeZone -> Int #

hash :: TimeZone -> Int #

Constructors

utc :: IO TimeZone Source #

Load the UTC time zone

localZone :: IO TimeZone Source #

Load the locally configured time zone (operating system configuration dependant)

timeZone :: String -> IO TimeZone Source #

Load the specified time zone. The time zone name should be in the format returned by availableZones

availableZones :: IO [String] Source #

List all time zones available to hodatime
