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