Re: [calsify] JSCalendar: alternative to current all-day events

[Michael Douglass <[e-mail]>]

Putting aside the  exact representation for the moment there is a need - 
expressed by calendar users - to represent what they mean by "all day".

For birthdays etc the current date-only is probably fine (though 
possibly being able to flag these as anniversary events might be useful).

However, for public and social events things are different. These are 
generally known as 'all day' - the start and end may be ill-defined if 
at all. They also often take place in a specific timezone.

For years creators of ics files have been trying to put timezones on 
dates. I tell them they can't - they say why? The only answer is that 
the standard says so. They want to flag an all day event as taking place 
in a certain timezone. Setting the start and end to midnight doesn't 
have the same meaning - that is a 24hour event.

The uis for public calendars need to know the difference between a true 
24hour event and an all-day event in a certain timezone - we display 
them differently.

So I think the first issue is to decide whether our users are simply 
being unreasonable or if they have a genuine unfulfilled need.

If you want an analogy - we can either see where people walk and then 
lay down the paths or we can lay the paths and forever repair the grass.
