[9fans] a strange time stamp

[arisawa]

Hello, 9fans.

I noticed a strange time stamp in /n/9fat.

term% cat /adm/timezone/local; date; touch /tmp/x; ls -l /tmp/x; 9fat:; touch /n/9fat/x; ls -l /n/9fat/x
JST 32400 JST 32400

--rw-rw-rw- M 95 bill trog 0 Aug 4 07:55 /n/9fat/x
term%

Why /n/9fat/x is Aug 4 07:55.
Is is only for me?

it's for everybody. dosfs is evidently saving in gmt,
(incorrect) and then reading in local time (correct).
this means that your tz offset gets applied twice.
since i'm gmt-4, the round trip to dosfs will give
gmt-8. if you're gmt+9, then the round trip would
yield gmt+18, i think.
