It should be simple, but it’s not. I made the mistake a few years ago, of writing a shell script which used GNU’s ‘%s’ switch… I didn’t think to test it on Solaris, but the person I’d written the script for was running Solaris, which has same (UNIX) syntax as AIX. The workaround I used was to write a very small C program, like this:

/* start of C program */
#include
#include

int main()
{
time_t t;
(void)time(&t);
printf(“%d\n”, t);
}
/* end of C program */

This provides the same output as `date +%s`:

$ ./d ; date +%s
1174077604
1174077604
$

Great tutorial, now I have a special twist and question for you. I am on an AIX host which for whatever reason IBM decided not to use GNU date. I have two existing dates already pulled from a log file and I would like to get the time between them. Generally I would use the same method you do only like this: $date -d “Fri Mar 16 12:06:03 MST 2007″ +%s, but an input option does not exist on AIX’s date command to use another date besides sysdate Is there any other way that you know of to take an existing date string and convert it into seconds from the unix epoch? I’ve thought about doing it in temp tables in Oracle, but that’s an overly taxing way to handle what should be a quick timestamp calculation…
