Remarks:
Converts local time to a calendar value.
<time.h>
time_t mktime(struct tm *tptr);
tptr
Returns the calendar time encoded as a value of time_t.
If the calendar time cannot be represented, the function returns -1, cast
as a time_t (i.e. (time_t) -1).
#include <time.h>
#include <stdio.h> /* for printf
int main(void)
{
}
Output:
Local time = Mon Oct 20 16:43:02 2003
Calendar time as time_t = 1066668182
Formats the time structure to a string based on the format parameter.
<time.h>
size_t strftime(char *s, size_t n,
s
n
format
tptr
Returns the number of characters placed in the array s if the total
including the terminating null is not greater than n. Otherwise, the func-
tion returns 0 and the contents of array s are indeterminate.
The format parameters follow:
%a abbreviated weekday name
%A full weekday name
%b abbreviated month name
%B full month name
%c appropriate date and time representation
%d day of the month (01-31)
%H hour of the day (00-23)
