I am developing my first Moodle plugin, and was looking for documentation on the moodle form date_time_selector object with little luck.
I would like a user to only be able to select a date and time that is in the present or future (it is used to book a video conference, and wouldn't be too useful if a user could book a conference in the past :P)
I figured I would be able to do it with the addRule function, but I'm not finding any documented way to do so.
Any help would be appreciated. Thanks in advance
