UNIX timestamp help.

[Namadoor]

Hello, I have this var that is a unix timestamp, and I want to add 1 hour (3600 seconds) to it, times the offset number. I have tried to do it like this:

$timestamp = $timestamp+(3600$offset);
and
$timestamp = (3600$offset);

But it isn't working.

How would be the correct way to do this?

Not sure which one you want, add them first or multiply them first... so I listed both.

$timestamp = time() + 3600;
$offset = 12345;
$blah = $timestamp * $offset;

or

$timestamp = time();
$offset = 12345 * 3600;
$blah = $timestamp + $offset;
