Thanks.

Don't bother with this. I found a solution that does not use
strptime(). ChatGPT gave me the programs.

At least Slackware 15.0 has a man page for strptime. Did you try to

#define _XOPEN_SOURCE

before your

#include <time.h>

?

I never used it but but I see that is included in the standard library.
Did you try "man strptime"?

He didn't bother. He's just a code monkey, copying code "written" by a
Large Language Model, and doesn't really know what he's doing.

Thanks for responding Henrik. No, I know know nothing
about _XOPEN_SOURCE.

I never thought to do man strptime. Right at the top
it gives the XOPEN thing. I was trying various
lib things.

It sure seems lile that, but I have been coding for seventy years.
I am working on a larger project and needed to pop back and
forth between different date formats including seconds from
epoch. I saw two options: 1) could try to work out the
details myself, 2) I could use popen and pass the problem
to a system call. I wanted to do it faster than either
1 or 2, so I thought I would give an AI a chance to
help. Try it yourself sometime.

When encountering something on a Linux machine (esp. a library
function) for which you are unfamiliar, your very first thought should *always* be: "lets check for a man page".

It will be my first step from now on. Thanks for responding.
