Yes, this is basically what I have in mind: a very simple format similar
to application/x-color in spirit (where we also omit colorspace, gamma,
and other things which 90% of the destinations probably don't have a use
for anyway).

Regarding the inclusion of time, I have thought about this some more and
think that it would be better to have separate formats for date+time and
time. The reason is that it is likely that a destination accepts date
but has no use for time information (like GtkCalendar). If time is an
optional part of a combined format, this decision can't be made based on
the type, but one has to actually get the data, see what it contains,
and then reject time-only information.
