Summary: Update 'The date/time prompt' section of Org Manual with time range specs. Comments: Support for specifying the duration in absolute minutes could be useful in some cases. (In my case, I was trying to plug in the duration of a BBC production specified in minutes - for eg 92 min, 116 min, 205 min etc). Related bugs: 1. While trying to specify time range as '2:00-3:00' I see the following message - 'Error in post-command-hook: (parse-error not an integer 3:)'. The corresponding calendar entry gets created though. 2. Is there support for agenda to wrap around the day. For example how would the following entries be interpreted 23:00+2:00, 3:00+48. Just curious.
