**`struct tm`** is a structure defined in the `time.h` header file in C language. Each of the member objects of `struct tm` contains the time and date stored on a machine. 

Below is a table that outlines what each member of the `struct` holds. The Daylight Saving Time flag is positive if it is daylight saving time, negative if it is unknown, and 0 if it is not daylight saving time. All the members are of type `int`.

# Example

The code below illustrates how you can use `struct tm` to print the calendar time and date. ﻿T﻿he values for the members of the struct are set to Mon Feb 1 01:01:01 1901 ﻿using the `(.)` operator﻿.

#include<stdio.h>
#include<time.h>

int main() {
  struct tm value;
 
  
  value.tm_sec=1;
  value.tm_min=1;
  value.tm_hour=1;
  value.tm_mday=1;
  value.tm_mon=1;
  value.tm_year=1;
  value.tm_hour=1;
  value.tm_wday=1;
  value.tm_yday=1;
   
  printf("Time and date: %s", asctime(&value));
  return 0;
}

Member
tm_sec	seconds passed since last minute
tm_min	minutes passed since hour
tm_hour	hours passed since midnight
tm_mday	day of the month
tm_mon	months passed since January
tm_year	year passed since 1900
tm_wday	days since Sunday
tm_yday	days since first day of the year
tm_isdst	Daylight Saving Time Flag
