Getting Date to payment gateway

[tolu]

Hi.

I´m trying to develope a custom payment gateway and I need to create a form and post forward.

My problem is that I need to somehow get fate into system in YYYYMMDD.

In my gateways interface description I need to get this info for DELIVERY_DATE

 

Here is a copy of the desc.

"Delivery date. The best estimate of the date of delivery of the goods. If the exact delivery date is not

known; using the latest possible date of delivery. Charges will be sent to the buyer with a credit facility

delivery date."

 

I found that from settings I can set up YYYY-MM-DD but how can it be modified?

 

Please someone help me how to get my php code working.
