Perderabo,
Here is the man page of ksh which describes it like this.

SECONDS Each time this variable is referenced, the
number of seconds since shell invocation is
returned. If this variable is assigned a
value, then the value returned upon reference
will be the value that was assigned plus the
number of seconds since the assignment.

Thanks for your suggestion. It looks like SECONDS is what I was looking for.

You're right. It's seconds since shell was started. But if you set it, it starts counting from where you set it. In my .env file I have:
((SECONDS = $(date "+3600*%H+60*%M+%S") ))

and, gosh, I just figured that everyone does that! Smilie

Seriously, I did that so long ago that I forgot.
