Data.Time.LocalTime

Time zones

data TimeZone

A TimeZone is a whole number of minutes offset from UTC, together with a name and a "just for summer" flag.

Constructors

TimeZone

Fields

• timeZoneMinutes :: Int

  The number of minutes offset from UTC. Positive means local time will be later in the day than UTC.

• timeZoneSummerOnly :: Bool

  Is this time zone just persisting for the summer?

• timeZoneName :: String

  The name of the zone, typically a three- or four-letter acronym.

Methods

iso8601Format :: Format TimeZone

timeZoneOffsetString :: TimeZone -> String

Text representing the offset of this timezone, such as "-0800" or "+0400" (like %z in formatTime).

timeZoneOffsetString' :: Maybe Char -> TimeZone -> String

Text representing the offset of this timezone, such as "-0800" or "+0400" (like %z in formatTime), with arbitrary padding.

minutesToTimeZone :: Int -> TimeZone

Create a nameless non-summer timezone for this number of minutes.

hoursToTimeZone :: Int -> TimeZone

Create a nameless non-summer timezone for this number of hours.

utc :: TimeZone

The UTC time zone.

getTimeZone :: UTCTime -> IO TimeZone

Get the configured time-zone for a given time (varying as per summertime adjustments).

On Unix systems the output of this function depends on:

1. The value of TZ environment variable (if set)
2. The system time zone (usually configured by /etc/localtime symlink)

For details see tzset(3) and localtime(3).

Example:

> let t = UTCTime (fromGregorian 2021 7 1) 0
> getTimeZone t
CEST
> setEnv "TZ" "America/New_York" >> getTimeZone t
EDT
> setEnv "TZ" "Europe/Berlin" >> getTimeZone t
CEST

On Windows systems the output of this function depends on:

1. The value of TZ environment variable (if set). See here for how Windows interprets this variable.
2. The system time zone, configured in Settings

getCurrentTimeZone :: IO TimeZone

Get the configured time-zone for the current time.

Time of day

data TimeOfDay

Time of day as represented in hour, minute and second (with picoseconds), typically used to express local time of day.

TimeOfDay 24 0 0 is considered invalid for the purposes of makeTimeOfDayValid, as well as reading and parsing, but valid for ISO 8601 parsing in Data.Time.Format.ISO8601.

Constructors

TimeOfDay

Fields

• todHour :: Int

  range 0 - 23

• todMin :: Int

  range 0 - 59

• todSec :: Pico

  Note that 0 <= todSec < 61, accomodating leap seconds. Any local minute may have a leap second, since leap seconds happen in all zones simultaneously
