%; mhical.12hour
%; Form file for mhical that directs it to use 12-hour instead of 24-hour
%; time format.
%;
%; See mhical.24hour for list of supported components.
%;
%; Here's what it does to the %{dtstart} special component:
%;
%; 1) Enable bold, and if the terminal supports color, green attributes.
%; 2) If the time zone is explicit, coerce the date to the local time zone;
%;    otherwise, assume that it's a floating time.
%; 3) Output the date in "ddd DD MM YYYY" format.
%; 4) Convert hours from 24- to 12-hour clock and output them as soon as
%;    they are calculated.  Store AM or PM in the str register.
%; 5) Output :minutes.
%; 6) Output AM or PM.
%; 7) If the time zone is explicit, output it.
%; 8) Reset all terminal attributes.
%; The timezone is not output for the dtend component because it is
%; almost always (except across a daylight saving time transition)
%; the same as for the dtstart component.
