44 Ptime has platform independent POSIX time support in pure OCaml.
45 It provides a type to represent a well-defined range of POSIX timestamps
46 with picosecond precision, conversion with date-time values, conversion
47 with RFC 3339 timestamps and pretty printing to a human-readable,
48 locale-independent representation.
49
50 The additional Ptime_clock library provides access to a system POSIX clock
51 and to the system's current time zone offset.
52
53 Ptime is not a calendar library.
