Issue #11886: workaround an OS bug (time zone data) in test_time

Australian Eastern Standard Time (UTC+10) is called "EST" (as Eastern Standard
Time, UTC-5) instead of "AEST" on some operating systems (e.g. FreeBSD), which
is wrong. See for example this bug:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=93810
