Description

An Instant is universal fixed moment in time.

Synopsis

data Instant
fromSecondsSinceUnixEpoch :: Int -> Instant
now :: IO Instant
add :: Instant -> Duration -> Instant
difference :: Instant -> Instant -> Duration
minus :: Instant -> Duration -> Instant
inTimeZone :: IsCalendarDateTime cal => Instant -> TimeZone -> ZonedDateTime cal

Types

data Instant Source #

Represents a point on a global time line. An Instant has no concept of time zone or calendar. It is nothing more than the number of nanoseconds since epoch (1.March.2000)

Constructors

fromSecondsSinceUnixEpoch :: Int -> Instant Source #

Create an Instant from an Int that represents a Unix Epoch

now :: IO Instant Source #

Math

add :: Instant -> Duration -> Instant Source #

Add a Duration to an Instant to get a future Instant. NOTE: does not handle all negative durations, use minus

difference :: Instant -> Instant -> Duration Source #

Get the difference between two instances

minus :: Instant -> Duration -> Instant Source #

Subtract a Duration from an Instant to get an Instant in the past. NOTE: does not handle negative durations, use add

Conversion

inTimeZone :: IsCalendarDateTime cal => Instant -> TimeZone -> ZonedDateTime cal Source #

Convert Instant to a ZonedDateTime in the specified time zone. The calendar must be derivable or specified in the type explicitly
