A high-performance time library 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.

Time to manipulate time A simple type useful for representing timestamps as generated by system events, along with conveniences for converting between time types from common Haskell time libraries. Our original use was wanting to conveniently measure things happening on distributed computer systems. Since machine clock cycles are in units of nanoseconds, this has the nice property that, assuming the system clock is not corrupted, two subsequent events from the same source process are likely to have monotonically increasing timestamps. And even if the system clock has skew, they're still decently likely to be unique per device. These TimeStamps thus make good keys when building Maps. The core type is in Chrono.TimeStamp, see there for full documentation.
