I want to take a timestamp from my database and increase in time(make it later) when I click on a button(This is not the problem though). With the timestamp I want to see how much longer till then from now. How would I do this? Thanks.
assuming they’re unix timestamps, you can do that right from the mysql query. i’m not sure of the exact query function, but any search engine can give you that 
You can use PHP’s DateDiff function…
I save my timestamps this way: date(‘Y-m-d H:i:s’)
I store it in a field called TimeStamp.
When needed in a page I use a variable like this: $timestamp=date(‘Y-m-d H:i:s’);
DateDiff is a little tricky as you have to tell it exactly what you what to compare, but here is the link:

Hope this helps…
