Bash 4.2 printf %()T seems to ignore TZ

[Dennis Williamson]

When I ran make test I noticed a discrepancy in a couple of the times
output during the printf tests. I pulled out the relevant section and
this is what I get:

LC_ALL=C
LANG=C
SECS=1275250155
export TZ=EST5EDT
printf "%()T\n" $SECS
printf "%(%e-%b-%Y %T %Z)T\n" $SECS  # added %Z

result:

15:09:15
30-May-2010 15:09:15 CDT

printf.right says it should be "16:09:15" in both cases. Note that the
%Z I added outputs CDT.

The next part of the test that compares date +%s passes.

Also:

$ LC_ALL=C LANG=C TZ=EST5EDT date -d @$SECS
Sun May 30 16:09:15 EDT 2010
$ TZ=EST5EDT date -d @$SECS
Sun May 30 16:09:15 EDT 2010
$ date -d @$SECS
Sun May 30 15:09:15 CDT 2010
