Thread: what happened to the function today

Hi
I have this function, I built 2 days ago, yesrterday it was working perfectly, today not.

Code:

char *month(int months, const char *format, char *text, size_t size)
{
   time_t t;
   if ( time ( &t ) != (time_t)(-1) )
   {
      struct tm *local = localtime ( &t );
      if ( local )
      {
         local->tm_mon += months;
         t = mktime ( local );
         if ( t != (time_t)(-1) )
         {
            local = localtime ( &t );
            if ( local )
            {
               if ( strftime ( text, size, format, local ) )
               {
                  return text;
               }
            }
         }
      }
   }
   return 0;
}

I use this function to bring the file of this month, like where are in month 2, so it suppose to bring me the file of month2 daily_report_02.txt , yesterday it brought it to me but today it suppose to bring the same file as we are still in month 2, but it brought me daily_report_03.txt, WWWWWWWWWHyyyyy


notice please
one final this because I read a input file of the previous day, so the out put should be put in the same month, what I mean is if today is 1 feb so my code will read the input file of the 31/1/2006 and will put its out put in Jan (Summary_Report_01.txt).
I use this function and call it in main

Code:

( notes field contain the path)
    string outpath= field + month(-1, "Daily_Report_%d.txt", outfile, sizeof outfile) ;
ofstream outfile(outpath.c_str(), ios::out | ios::app);

please fix my error
