New datetime c

You're looking for information on the new datetime C library!

The datetime library is a part of the C standard library, and it provides functions for working with dates and times. Here's a brief overview of the new features and changes in the datetime library:

New Features:

  1. struct tm: The struct tm type has been updated to include additional fields for leap seconds and timezone information.
  2. mktime: The mktime function now returns the number of seconds since the epoch (January 1, 1970, 00:00:00 UTC) instead of the number of seconds since the start of the day.
  3. localtime: The localtime function now returns a pointer to a struct tm object that includes timezone information.
  4. gmtime: The gmtime function now returns a pointer to a struct tm object that includes timezone information.
  5. strftime: The strftime function now supports additional format specifiers for dates and times.

Changes:

  1. time_t: The time_t type has been updated to be a 64-bit integer, which allows for a larger range of dates and times.
  2. clock: The clock function has been removed, as it was deprecated in earlier versions of the C standard.

Example Code:

Here's an example of how you can use the new datetime library:

#include <datetime.h>

int main() {
    struct tm *tm = localtime();
    printf("%04d-%02d-%02d %02d:%02d:%02d\n",
           tm->tm_year + 1900, tm->tm_mon + 1, tm->tm_mday,
           tm->tm_hour, tm->tm_min, tm->tm_sec);

    return 0;
}

This code uses the localtime function to get the current date and time, and then prints it in the format YYYY-MM-DD HH:MM:SS.

Note that the datetime library is still evolving, and new features and changes may be added in future versions of the C standard.
