Then you should look into sprintf(), which just returns the result.
$oneHourAgo = sprintf("%02d",$hour--);
I think.

Subject: Calculate previous hour?
Hello all,
Well, I've got a very simple problem and can't seem to get the answer I
want.
Basically I just want to find the previous hour in one of my scripts.
This code does it, but I need to maintain the format "09".
$hour = (localtime)[2];
$hour--; #adjust hour to previous
I know about using printf, but I don't need to print this value. I need
to use it as a variable.
I've even tried stuff like this:
$prevhour = &DateCalc("today","- 1hour","%H");
print "prev hour: $prevhour\n";
but it gives me the whole date.
It seems to me that to achieve something so simple wouldnt' be so
difficult.
Any ideas?
Thanks,
Kevin
