How can I make the "add event" dialog in Lightning use 12-hour times?

The Add Event dialog in Lightning (on an iMac running OS 10.10.2 Yosemite) is displaying 24-hour times in the dropdown boxes. I need these to be in 12-hour format.

Also, the default calendar needs to be changed. Where are these preferences located?

I don't know what the acceptable setting values are, but you could experiment with

calendar.date.format

in the config editor. Tools|Options|Advanced|General→Config editor

Mine is set to 1 and it's faithfully copying the date/time format I use elsewhere, but that may just be coincidence. But I suspect it is simply the toggle between long and short date formats as offered in the Options GUI for the calendar.

Bear in mind that all those AM/PM indicators will eat up precious screen real estate.

Settings for the Calendar are under Tools|Options (on Windows); that'll be Edit|Preferences or Thunderbird |Preferences.
