|
|
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.
