| Well, it doesn't refer to a file, and it doesn't change the way

Now I know you have absolutely no idea what you're talking about ...
brandenburg$ ls -lut /etc/passwd; TZ=/etc/passwd date; ls -ltu /etc/passwd
-rw-r--r-- 1 root wheel 762 Nov 19 03:26 /etc/passwd
Sun Nov 19 10:40:25 GMT 2000
-rw-r--r-- 1 root wheel 762 Nov 19 17:40 /etc/passwd
I'm currently at UTC+0700 (ie: 10:40 GMT == 17:40 local).
Now, which file was that that TZ doesn't refer to?
If I had a tape on this laptop, I'd rewind it, just to demonstrate,
but I don't, so you'll have to do that part yourself...

It isn't a fix to the problem, only to one symptom of the problem.
And it is a "fix" that breaks a useful feature (whether you find it
so or not, I *like* to ping/traceroute/... to things in my $HOSTALIASES).
For "ping: to not find the same host as "telnet" finds, no matter what
the name I use to access it, would be a serious bug IMO.
