Dixi quod=E2=80=A6

>Now, I=E2=80=99m suspecting a timing issue or something, so if anyone

=E2=80=A6 but while writing that, I saw this:

>=09Argument [34] Oct 1999 [0-9][0-9]:00:00 -0000

>=09Argument 3 Oct 1999 23:59:38 -0000

That made me curious, and indeed:

tg@blau:~ $ date; TZ=3DUTC0 date; TZ=3D date
Sat Oct 22 18:50:58 UTC 2016
Sat Oct 22 18:50:58 UTC 2016
Sat Oct 22 18:51:24 UTC 2016

So sanity.sh (which, IMHO, probably ought to have been called
insanity.sh instead =E2=98=BA) fails to properly restore an unset $TZ.

Fix attached for your convenience.
