Re: [web-annotation] 'generated' and 'modified' should use UTC by default

@iherman No, I'm not suggesting that you `require UTC`. I'm pointing 
out that timestamps all map to (UTC-based) epoch times. That is, these
 are the same:

   2016-05-18T00:00:00Z
   2016-05-18T08:00:00+08:00

But it should be noted that +08:00 is not a time zone and the above is
 not obvious.

And actually, timestamps aren't the problem. The problem is with 
floating time values. For example, in a few places in the document you
 refer to specific date versions of a resource (the example I use in 
my day job would be a specific Sunday New York Times edition). The 
date of that resource should not be effected by the local time zone on
 display. If timestamps are permitted for floating time values (which 
you might want to avoid creating in the first place), then you'll have
 problems with the date changing for people with different local 
times.
