The time.h header defines four variable types, two macro and various functions for manipulating date and time. A brief description of the variable types defined in the header time.h is as :
- size_t : This is the unsigned integral type and is the result of the sizeof keyword.
- clock_t : This is a type suitable for storing the processor time.
- time_t is : This is a type suitable for storing the calendar time.
- struct tm : This is a structure used to hold the time and date.
