How can I launch the Lightning-"create Event"-Dialog with given Date and Time

Question

I would like to open the thunderbrid-lightning-create event dialog with a given date and time. Currently I have:

window.open("chrome://calendar/content/calendar-event-dialog.xul",
                      "xulschoolhello-some-window",
                      "chrome,centerscreen")

Which opens the Dialog as expected. How can I set now the Date and Time?

Check out the openEventDialog function, which also defines some window arguments down in line 434 if you want to do it manually.

/**
 * Opens the event dialog with the given item (task OR event)
 *
 * @param calendarItem      The item to open the dialog with
 * @param calendar          The calendar to open the dialog with.
 * @param mode              The operation the dialog should do ("new", "modify")
 * @param callback          The callback to call when the dialog has completed.
 * @param job               (optional) The job object for the modification.
 * @param initialDate       (optional) The initial date for new task datepickers
 */
function openEventDialog(calendarItem, calendar, mode, callback, job, initialDate) 

You can call this function directly on the window object of the main Thunderbird window. This could for example be done by adding a XUL overlay to the window that has a script block that eventually calls this function.
