posixtm failure on Solaris

[Bruno Haible]

Hi Paul,

On Solaris 11.3, Solaris OpenIndiana, and Solaris OmniOS, I'm seeing this
test failure:

000001010000.00 mismatch (-: actual; +:expected)
--62167132800
+-62167219200
000012312359.59 return value mismatch: got 0, expected 1
FAIL test-posixtm (exit status: 1)

It was already reported in 2011 [1], and you said
"(Programmers get confused near the year zero,
 for some reason.  :-)  It's probably not worth worrying about."

I'm tired to see the same test failures over and over again. So I'm disabling
these tests on Solaris. Since, as you said, it's not worth worrying about,
I would guess that there is no need to update the documentation?
