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