wget: Checking for file timestamp and overwriting.

Hi all.

How can I get wget to do this:

Download a file from a location say x, only if the local copy of the file has an older time stamp than that of the file's time stamp on x. That means, it should download a file from a given location, only if there is a newer version of the file.

In case there is a newer version of the file, wget should overwrite the file.

Is it possible to do this?
