Does Emacs Org Mode have a concept of "durations"? Specifically I want to define durations in years, months, weeks, and/or days, and then sort a column of such data.
- Emacs has such a concept, but how to use?
- There exist string standards for such durations, where? And which is the easiest to type in as a human?
- Make up a string definition for durations. E.g. 1-5-3-2 (1 year, 5 months, 3 weeks, 2 days). And if there is no year you'd just do: 0-5-3-2 so it's sortable, etc.
