The asctime function

Name

asctime -- Transform binary date and time to ASCII

Synopsis

#include <time.h>

char *asctime (const struct tm *timeptr);

Description

The asctime function converts the broken-down time in the structure pointed to by timeptr into a string in the form:

Sun Sep 16 01:03:52 1973\n\0

using the equivalent of the following algorithm.

char *asctime(const struct tm *timeptr)
{
  static const char wday_name[7][3] = {
        "Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"
  };
  static const char mon_name[12][3] = {
        "Jan", "Feb", "Mar", "Apr", "May", "Jun", 
        "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"
  };
  static char result [26];
  sprintf(result, "%.3s %.3s %.2d %.2d:%.2d:%.2d %d\n",
          wday_name[timeptr->tm_wday], 
          mon_name[timeptr->tm_mon],
          timeptr->tm_mday, timeptr->tm_hour, 
          timeptr->tm_min, timeptr->tm_sec, 
          1900 + timeptr->tm_year);
  return result;
}

Returns

The asctime function returns a pointer to the string.
