<li>A 2-digit year is interpreted to be a year in 1950-2049.</li>

<li>Single letter ‘military’ time zone names are parsed as a <code>-0000</code> offset.
They were defined with the wrong sign in RFC 822 and corrected in RFC 2822. But because
the meaning is now ambiguous, the standard says they should be be considered as <code>-0000</code>
unless there is out-of-band information confirming their meaning.
The exception is <code>Z</code>, which remains identical to <code>+0000</code>.</li>
