Adding time

[pauly]

I am passing a variable ($emailt) that is a number of hours to a PHP page that then sends an email. I want to add the current time to the number of hours variable and send it in the email. The variable is usually either 12 or 24 .
If the current time is 7:05 pm I want to add 12 so that the variable would read 7:05am. What I have so far is giving me 7:00 am and no exact minutes.
How do I add the two times together correctly?

  $time = date("g:i a");
	 $emailt = ($emailt*3600+$time);
	 echo date("g: i a",$emailt) ;

OK, I think you just want to use the current value of time() as a UNIX timestamp integer, then only use date() when you output it in human-readable format:

$emailt = ($emailt * 3600 + time());
echo date("g: i a", $emailt) ;

Thanks NogDog, that worked!
