Functions

Defined in header <ctime>
Time manipulation
computes the difference between times
(function)
returns the current time of the system as time since epoch
(function)
returns raw processor clock time since the program is started
(function)
(since C++17)
 returns the calendar time based on a given time base
(function)
Format conversions
converts a tm object to a textual representation
(function)
converts a time_t object to a textual representation
(function)
converts a tm object to custom textual representation
(function)
converts a tm object to custom wide string textual representation
(function)
converts time since epoch to calendar time expressed as Universal Coordinated Time
(function)
converts time since epoch to calendar time expressed as local time
