Summary: email.Utils.formatdate(): localtime bug

Initial Comment:
email.Utils.formatdate(localtime=1) does 
not produce a correct UTC offset for 
"uneven" timezones (e.g, "+1030", "+0530")
In those cases, it rounds the offset down
to "+1000", and "+0500".

In the example below, you can see that
python produces the wrong UTC offset
once I set my TZ to "Australia/Adelaide",
a timezone whose offset should be "+1030".

$ date
Sun Nov 18 19:29:22 MST 2001
$ python2.2 -c 'import email;print 
email.Utils.formatdate(localtime=1)'
Sun, 18 Nov 2001 19:29:22 -0700

$ export TZ="Australia/Adelaide"
$ date
Mon Nov 19 12:59:35 CST 2001
$ python2.2 -c 'import email;print 
email.Utils.formatdate(localtime=1)'
Mon, 19 Nov 2001 12:59:35 +1000

Just to followup with some more info:

I forgot to mention I'm running Python 2.2b2
on FreeBSD 4.4-RELEASE.

Also, when investigating this problem, don't
forget timezones with negative fractional 
UTC offsets (e.g, -0330) in addition to positive.

Such is the case when TZ is "Canada/Newfoundland"
or "America/St_Johns" for example.
