confusion with adding 2 time values

Question

Basically this whole time stuff is frustrating me, I am new to programming so I do apologise if I am asking a stupid question.

I have a MySQL time() stored in my databas

Answer 1

Strtotime is propagating a date inside there, something like "6PM today", instead of 6 hours like you intend. The easiest way to do this is to run

time() + (6 * 3600);

Where 6 is hours, and 3600 is the number of seconds in each hour.
