header

C Time Library

This header file contains definitions of functions to get and manipulate date and time information.

Functions

Time manipulation

difftime Return difference between two times (function)
mktime Convert tm structure to time_t (function)
time Get current time (function)

Conversion:
asctime Convert tm structure to string (function)
ctime Convert time_t value to string (function)
gmtime Convert time_t to tm as UTC time (function)
localtime Convert time_t to tm as local time (function)
strftime Format time to string (function)

Macros

CLOCKS_PER_SEC Clock ticks per second (macro)
NULL Null pointer (macro)

types

clock_t Clock type (type)
size_t Unsigned integral type (type)
time_t Time type (type)
struct tm Time structure (type)
