Hi Ben,

extending the date format would be a significant amount of work.
The current time/date format is already complex to handle
internally, mainly because it was build not with a clean design
but step by step.  o I am hesitating to add something like
you propose.

My feeling is that date specifications like this are seldomly used,
and as far as readability is concerned, for these few events you
could just (as suggested by Matt) write a note explaining what
the entry does.

Sorry.

- Carsten
