Interval Profiling and TZ Services

["Toby Considine" <Toby.Considine@gmail.com>]

There are only two “components” in icalendar that are valid inside tasks, which would include vtodo and interval. They are valarms and timezones

 

There is no reason to include valarm n intervals. TimeZone components are a potential issue.

 

Recent directions in the CalConnect world are to declare a separate timezone server,  which eliminates the need to have a potentially large timezone component exchanged with each message. If we assume the existing of a timezone server in the EI standard, then Intervals have no need of components, only properties. This would go a long way toward simplifying Intervals, esp in that they would eliminate recursion.

 

So:

 

I recommend that we add a reference to a time zone server into the marketContext negotiations. The VTN or a 3^rd party could be the time zone server. All Time Zone information other than the top level name, then, leaves the messages of EI.

 

Draft RFC for a time zone service:
