timed locks?

[zcmrfrodo]

Hi,

I am currently looking for a lock that i could program to unlock at a certain time. For example, a lock that i could program to unlock a week from today. I need it for an extremely low security application, so I'm also looking for it to be cheap.

Does anyone know if a lock exists like this?

Thanks in advance for any responses.

Theres a lot of these types of access control lock popping up but i have yet to see one i would refer to as cheap.
