This change was released in tzdb 2019c on September 11, thanks to a notification by Kyle Czech on August 13. If you're running the most recently patched release of Debian, Fedora, etc. then Pacific/Norfolk should be working for you already. Here's what I see on my laptop running Ubuntu 18.04.3: $ date -u; TZ=Pacific/Norfolk date Sat Oct 26 17:20:05 UTC 2019 Sun Oct 27 05:20:05 +12 2019

Would the following be more informative, but perhaps less portable?: 1754 $ tail -1 /usr/share/zoneinfo/Pacific/Norfolk <+11>-11<+12>,M10.1.0,M4.1.0/3 -- gil

Whether this is what the poster expects from "the DST schedule of Australia", and even whether this project is relevant, depends on what system they are running, who the update org is, how up to date its timezone package is, and whether the system has been updated recently.

Maybe a bit less informative, unless you are into obscure codes: POSIX should have specified week of occurrence and day of week prefixes e.g. M01.W1.D0 and required at least 4 digit times e.g. /0300; they could even have supported alternative English month and day of week abbreviations (like Vixie cron since 1993!) and the string "last" instead of week 5 for the last week of the month. Command alternatives: $ TZ=Pacific/Norfolk date -u; TZ=Pacific/Norfolk date $ for opt in '-u' ''; do TZ=Pacific/Norfolk date $opt; done $ for tz in UTC Pacific/Norfolk; do TZ=$tz date; done To my mind the canonical command is probably: $ zdump -Vc$(date +%Y),$(date -d'next year' +%Y) Pacific/Norfolk Pacific/Norfolk Sat Oct 5 14:59:59 2019 UT = Sun Oct 6 01:59:59 2019 +11 isdst=0 gmtoff=39600 Pacific/Norfolk Sat Oct 5 15:00:00 2019 UT = Sun Oct 6 03:00:00 2019 +12 isdst=1 gmtoff=43200 showing that the change took effect Oct 5/6. This only works for zones observing annual DST. You need a wider year range where there are only zone offsets: 1970/1980-next. Use a profile alias or function for the messy bits. -- Take care.
