Australia/Melbourne is not a legal time zone name. Fix it on the Course Configuration page.

The trouble with this is that "Australia/Melbourne" IS a perfectly valid timezone, as checked on
and with the command:
perl -MDateTime::TimeZone -e 'print join "\n", DateTime::TimeZone::all_names'
I've had this problem before, and there was a problem between WeBWorK and Perl's timezone management, but even though I'd set one time (for a homework set due date), and WeBWorK would translate it into another time (for display), I never got all these warnings.
So how do I manage my timezone so that I don't get these warnings? Do I need to update any of my Perl modules? Or should I just set my timezone to be America/New_York and live with WeBWorK time and local time being 15 hours different? That is, should I remove any timezone settings in any of my *.conf files? I'm using WW and pg v2.10, under Ubuntu server 14.04, and "perl -v" gives me:
"This is perl 5, version 18, subversion 2 (v5.18.2) built for x86_64-linux-gnu-thread-multi (with 41 registered patches, see perl -V for more detail)"
Advice, as always, would be gratefully received. (Our teaching semester starts on Feb 29, and I hope to have it running smoothly then.)
