To whom it may concern, I am an end user of timezone data (tzdata) in a Linux distribution (Fedora). As the package ReadMe suggests, questions about the content of tzdata should be directed to this mailing list rather than the distribution's developers. In the Australian eastern zone, two time zones are used: Australian Eastern Standard Time (UTC +10) and Australian Eastern Daylight-savings Time (UTC +11). The abbreviations for these zones are AEST and AEDT, respectively. Australian timezones are explained here: http://www.australia.gov.au/about-australia/our-country/time The tzdata currently available for my Linux distro (which I believe is the latest available) uses the incorrect label "EST" for both AEST and AEDT. The timezone (+10 or +11) itself is correct, but the labels are not. Could you please look into this issue and, if it is indeed your responsibility, correct it at the next convenient opportunity. Kind Regards, RG
