how to java/javascript for created date -7 days

[t]

I created a custom calculated date field and i need it to look at the issues created date and minus 7 days from that... how can id o this? i have tried this - return issue.getCreated() - 7

It's certainly possible, but first of all I wanted to ask, why?

If you're only going to use JQL, then you could achieve the same thing with

created > "-7d"

Also, issue.getCreated() is of type Timestamp, so you can't just subtract from it, since it doesn't know what you are subtracting... 7 minutes? 7 days? 7 years? You have to use some other method to subtract so that it knows.
