[Developers] Calendar systems

[Alec Flett]

I have some experience with calendaring, etc, and I'd like to see MQL 
get a better understanding of some calendaring concepts like timezone.

At one point I asked in a discussion group somewhere about storing 
vCalendar data in the graph - but after reading some of the 
conversations here, and talking a bit with Tim Sturge, it seems prudent 
to come up with very specific things that we want to model so we can at 
least prioritize what is useful know, because of issues with:
- Timezones
- Recurrence & complex recurrence rules
- Calendar systems
- Relative dates & date math

 From what I understand Kirrily you're pretty familiar with these issues 
- I'm in support of importing as much of the raw standard calendar data 
as we can (i.e. timezones and the like)

Over time I think that we could get MQL to support a richer notion of 
date/time but I think it's important to understand what we want to model 
first...
