Possible to send a transaction with delayed payment?

Is it possible to do something like this:
"A" pays x bitcoins to "B", but wants B to be able to spend the x bitcoins no sooner than on some date that is pre-defined by "A". Does script allow this maybe?
If this is possible, "A" could send all his bitcoins to himself, but only allow himself to spend his funds after a certain date. This would temporarily freeze his funds and could be regarded as a present to the network: The money supply is temporarily provably reduced.

Interesting!
How would that work exactly? According to https://en.bitcoin.it/wiki/Script, script only has a limited set of instructions, and I fail to see anything related to time.
What also worries me is the statement "Note that there is a small number of standard script forms that are relayed from node to node; non-standard scripts are accepted if they are in a block, but nodes will not relay them.". Could it still be made to work somehow?
