c - 讀取系統的時間

讀取系統的時間

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

void main( void )
{
  struct tm *newtime;
  char am_pm[] = "AM";
  time_t long_time;
  time( &long_time );                /* Get time as long integer. */
  newtime = localtime( &long_time ); /* Convert to local time. */

  if( newtime->tm_hour > 12 )        /* Set up extension. */
    strcpy( am_pm, "PM" );
  if( newtime->tm_hour > 12 )        /* Convert from 24-hour */
    newtime->tm_hour -= 12;          /*   to 12-hour clock.  */
  if( newtime->tm_hour == 0 )        /*Set hour to 12 if midnight. */
    newtime->tm_hour = 12;
  printf( "%.19s %s\n", asctime( newtime ), am_pm );
}
