[ietf-calsify] Clarification on DUE in TODO's in rfc2445bis

[Nigel Swinson]

Sounds like another use case for saying something starts at 11am "ish! and 
is due by 6pm "ish".  Switching from date to date-time implies a degree of 
precision that might not be appropriate.  I'd very much like there to be 
better options for saying "I've arranged to have dinner with a friend on 
Tuesday evening", when the start/end time of that event have yet to be 
firmed up.
