Comment 1:

An RFC3339Nano bug was fixed in Go tip (which will be in Go 1.1).
But this isn't even valid:
    time.Parse(time.RFC3339, time.RFC3339)

Status changed to Invalid.

Comment 2:

Thank you for the update. Two things:
1. Why is time.Parse(time.RFC3339, time.RFC3339) invalid (I am sorry for being so
ignorant)?
2. I am sorry for wasting your time.

Comment 3:

The fixed bug was issue #3523.

Comment 4:

An RFC3339 can't contain both a "Z" (which means 00:00) and an offset.
In your examples,
2013-04-14T15:42:09.869934827Z04:00 -- contains both Z and 04:00
time.RFC3339 itself doesn't work as an input value because it's
2006-01-02T15:04:05Z07:00, which has both Z and an offset.
A time format isn't necessarily a valid input.  It's a description of how to parse a
time.

Comment 5:

Ah! I didn't understand the Z and offset thing - I guess I should have read up more on
the RFC3339 spec.
Thank you so very much for taking the time to explain that to me.
