Hello, i need some help, i'm creating a script and i need to convert normal date (24/05/07) in unix time, i see some web sites with calculators, but i need to put the code in my shell script. In the first time i thought that i will found that in google jeje, but i only found the inverse, unix time to normal date. Somebody can help me?. Thanks a lot.

After a quick google, I found the following page that should point you in the right direction, using perl...

Hey gbratig, Can you point me to the site where you saw the Epoch to normal date conversion?

compile this and call it from your script. You'll have to setup a template file, you can probably create it in your script and delete it before the script finishes.

Code:

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

main( int argc, char * argv[] )
{
   struct tm * timestruct;
   time_t epochtime;

   if ( getenv("DATEMSK") == 0 )
   {
      printf("\nSet environment variable DATEMSK to\n");
      printf("the file containing the date templates\n");
      printf("see 'man 3 getdate'\n\n");
      exit(-1);
   }

   if ( argc > 1 )
   {
      timestruct = getdate(argv[1]);
      epochtime = mktime( timestruct );
      printf("%ld\n", epochtime );
   }



}
