// OVERVIEW
|
|
//
|
|
// This section contains fundamental time types used internall by
|
|
// libtorrent and exposed through various places in the API. The two
|
|
// basic types are ``ptime`` and ``time_duration``. The first represents
|
|
// a point in time and the second the difference between two points
|
|
// in time.
|
|
//
|
|
// The internal representation of these types is implementation defined
|
|
// and they can only be constructed via one of the construction functions
|
|
// that take a well defined time unit (seconds, minutes, etc.). They can
|
|
// only be turned into well defined time units by the accessor functions
|
|
// (total_microseconds(), etc.).
|
|
//
|
|
// .. note::
|
|
// In a future version of libtorrent, these types will be replaced
|
|
// by the standard timer types from ``std::chrono``.
