created a separate item for a suggestion raised by MD on Item2915:

May I further propose that if the format string specifies hours and minutes that the calendar will allow to select date and time. This would require a small api change to showCalendar() adding a third argument (a boolean saying wether to also select a time or only a date ... a thing which is disabled in showCallendar() right now) and an analysis of the format string.

MD

Just to clarify... this requires

1. in pub/TWiki/JSCalendarContrib/twiki.js, add parameter to showCalendar to support setting cal.showsTime
2. when calendar is shown, need to set this new flag accordingly, maybe requiring analysis of the format string.

-- TW

Note that I reverted Item2815 because it breaks the combined mandatory and hidden feature and is non backwards compatible.

Ref Item3685?
