Ok, so you start your trial right now, so your Epoch time would be 1381857376, which is the number of seconds since 1/1/1970.

To add 7 days you would say
Sec*Min*Hrs*Days
60*60*24*7 = 604800

The trial would end at 1382462176 seconds.
which converts to Tue, 22 Oct 2013 17:16:16 GMT.

Here is a online converter that might give you some ideas, or just use to check your values.

Somewhere you would either record the trial start period or the trial end period and check that value each time your program runs.
