Chronos

Chronos is a performance-oriented time library for Haskell, with a straightforward API. The main differences between this and the time library are:

• Chronos uses machine integers where possible. This means that time-related arithmetic should be faster, with the drawback that the types are incapable of representing times that are very far in the future or the past (because Chronos provides nanosecond, rather than picosecond, resolution). For most users, this is not a hindrance.
• Chronos provides 'ToJSON'/'FromJSON' instances for serialisation.
• Chronos provides Unbox instances for working with unboxed vectors.
• Chronos provides Prim instances for working with byte arrays/primitive arrays.
• Chronos uses normal non-overloaded haskell functions for encoding and decoding time. It provides attoparsec parsers for both Text and ByteString. Additionally, Chronos provides functions for encoding time to Text or ByteString. The time library accomplishes these with the Data.Time.Format module, which uses UNIX-style datetime format strings. The approach taken by Chronos is faster and catches more mistakes at compile time, at the cost of being less expressive.

Functions

Current

now :: IO Time

Get the current time from the system clock.

today :: IO Day

Gets the current Day. This does not take the user's time zone into account.

tomorrow :: IO Day

Gets the Day of tomorrow.

yesterday :: IO Day

Gets the Day of yesterday.

todayDayOfWeek :: IO DayOfWeek

Get the current DayOfWeek from the system clock.

yesterdayDayOfWeek :: IO DayOfWeek

Get the yesterday's DayOfWeek from the system clock.

tomorrowDayOfWeek :: IO DayOfWeek

Get the tomorrow's DayOfWeek from the system clock.

timeToDayOfWeek :: Time -> DayOfWeek

Convert from Time to DayOfWeek.

epoch :: Time

The Unix epoch, that is 1970-01-01 00:00:00.

Duration

stopwatch :: IO a -> IO (Timespan, a)

Measures the time it takes to run an action and evaluate its result to WHNF. This measurement uses a monotonic clock instead of the standard system clock.

stopwatch_ :: IO a -> IO Timespan

Measures the time it takes to run an action. The result is discarded. This measurement uses a monotonic clock instead of the standard system clock.

Text

encodeTimespan :: SubsecondPrecision -> Timespan -> Text

Encode a Timespan as Text using the given SubsecondPrecision.

builderTimespan :: SubsecondPrecision -> Timespan -> Builder

Construct a Text Builder corresponding to an encoding of the given Timespan using the given SubsecondPrecision.

UTF-8 ByteString

encodeTimespanUtf8 :: SubsecondPrecision -> Timespan -> ByteString

Given a SubsecondPrecision, construct a ByteString corresponding to an encoding of the given Timespan.

builderTimespanUtf8 :: SubsecondPrecision -> Timespan -> Builder

Given a SubsecondPrecision, construct a ByteString Builder corresponding to an encoding of the given Timespan.

TimeInterval

within :: Time -> TimeInterval -> Bool

Is the given Time within the TimeInterval?

timeIntervalToTimespan :: TimeInterval -> Timespan

Convert a TimeInterval to a Timespan. This is equivalent to width.

whole :: TimeInterval

The TimeInterval that covers the entire range of Times that Chronos supports.

\(t :: Time) -> within t whole

singleton :: Time -> TimeInterval

The singleton (degenerate) TimeInterval.

lowerBound :: TimeInterval -> Time

Get the lower bound of the TimeInterval.

upperBound :: TimeInterval -> Time

Get the upper bound of the TimeInterval.

width :: TimeInterval -> Timespan

The width of the TimeInterval. This is equivalent to timeIntervalToTimespan.

timeIntervalBuilder :: Time -> Time -> TimeInterval

A smart constructor for TimeInterval. In general, you should prefer using this over the TimeInterval constructor, since it maintains the invariant that lowerBound interval <= upperBound interval.

(...) :: Time -> Time -> TimeInterval infix 3

An infix timeIntervalBuilder.

data TimeInterval

A TimeInterval represents a start and end time. It can sometimes be more ergonomic than the Torsor API when you only care about whether or not a Time is within a certain range.

To construct a TimeInterval, it is best to use timeIntervalBuilder, which maintains the invariant that lowerBound interval <= upperBound interval (all functions that act on TimeIntervals assume this invariant).

TimeInterval !Time !Time
