chronos: A performant time library
This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.
Warnings:
- 'ghc-options: -O2' is rarely needed. Check that it is giving a real benefit and not just imposing longer compile times on your users.
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 http://hackage.haskell.org/package/time 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.
