Sure, but there are potential privacy concerns here.  Sending UTC always does 
not give away my (extremely broad) geographical location, while including the 
timezone offset does.

I am not suggesting we force this 'stamp' to always be UTC.  Personally, I 
think I might like the timezone offset to be included (my last is 3 hours ago 
because it's the middle of the night for me compared to you").  What I am 
suggesting is adding a note somewhere about the concern.
