Re: [HC Evolution] Calendar to-do list

Yup - this is a big problem since all events/schedules and stuff are stored
in time_t format I believe. I think it can be done via the UI though. Say
for example I want to schedule something while in "Islamic Mode". I have a
UI option (radio buttons?) to choose between either:
A) A "fixed" mode. - this event will occur on 2nd of Ramadan regardless of
whether the leap month occurs or not
or
B) A "rolling" mode - This event will occurs 2 days after "Sha'aban" has
ended (i.e. this takes into account whether the leap months occur or not).

The problem is how does the /native/ file format (vCalendar or iCalendar?)
handle that? It doesn't as far as my knowledge goes. Russel Steinthal
mentioned some sort of "property" we can set. But i can't decipher RFCs and
stuff.

You could of course come up with your own file format (or write up something
in the spec and submit it - but that will be A) Time Consuming and B) Very
difficult)
