Question

Alright, I have a field which is called timestamp and it is formatted as such:
00/00/00 00:00:00 and I want to grab that field and then updated it in int timestamp form to a field called tm_unix. So how would I do that with a single update? I can do it as a php loop but thought there has to be a way to do it mysql and just need a quick answer.

Unless someone can tell me how to find less than 30 days on the format 00/00/00 00:00:00?

Thanks

Edit: I am using mysql4
