Event durations are pretty straight forward to denote:
<2015-08-27 Thu 14:30-21:00>
But what about an event that extends past midnight?
<2015-08-27 Thu 22:30-01:30>
Does not do what I think it does. Additionally, giving the date/time prompt something like
21:00+4 will result in a timestamp such as:
<2015-08-27 Thu 21:00-25:00>
What is the correct way to denote such an event?
