This has been a recurring proposal on this list, most recently in October 2012: http://thread.gmane.org/gmane.comp.time.tz/5518 http://thread.gmane.org/gmane.comp.time.tz/5654 The general consensus around here for many years has been that this is a WONTFIX, unless perhaps it becomes more clear over time that, e.g., CDT is in much more common use than CST to describe the time during summer in Australia. So far, there hasn't been a lot of convincing data on that, although some trends have been noted: http://thread.gmane.org/gmane.comp.time.tz/5518/focus=5595 -- Tim Parenti On 7 January 2013 14:53, <kavi@postpro.net> wrote:

The upshot: Australia/South observes daylight savings time, but the tzdata entry specifies 'CST' as the abbreviation year round. Is this a problem?
