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)

Instances

Instances details

Show Instant Source #	A debug rendering exposing the internal epoch-relative fields (epoch is 1.March.2000). There is no clean total constructor to reproduce an arbitrary `Instant`, so this is deliberately a labelled view, not a call.

Constructors

fromSecondsSinceUnixEpoch :: Int -> Instant Source #

Create an Instant from an Int that represents a Unix Epoch

The current time as an Instant.

Note: Hoda Time does not model leap seconds, so now follows POSIX time semantics — the returned Instant does not include leap seconds (every day is treated as exactly 86400 seconds). This keeps now consistent with the rest of the library: round-tripping through a ZonedDateTime never adds or removes leap seconds.

now :: IO Instant Source #

Math

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

Add a Duration to an Instant to get a future Instant.

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.

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
