Selected date/time when add an event using double-click

Hi,

I use a custom form to edit an event. I want to set the date for it with the date/time the user double click to add an event.

Where do I get it from?

Thanks,
Bogdan.

scheduler.showLightbox = function(id){ var ev = scheduler.getEvent(id); //ev.start_date - date for which new event was created
