Manually Create Orders

Hi,

There is no option in the interface to change the date of an order.
If you want to change all the dates of all the orders you just added, you can use a mass action via the menu System>Mass actions, with an action "update the values" on the order_created_date column with the value being equal to the timestamp you want:

If you want to create orders manually, you can use the "new" button on the orders listing, select the user, the products etc.
If you don't have yet the user created, you will have to first add it via the Joomla user manager.
An alternative is to create the order through the normal checkout interface on the frontend.
