            date command doesn't know "EDT" timezone. If a timezone which isn't supported is passed in TZ the output will indeed show with entered time zone but time shown will be UTC.



            Supported time zones are listed in /usr/share/zoneinfo/. As of now time zones that can be used as a value for "TZ" are:



            Africa Cuba GMT0 Japan Pacific Turkey
            America EET GMT-0 Kwajalein Poland UCT
            Antarctica Egypt GMT+0 leap-seconds.list Portugal Universal
            Arctic Eire Greenwich Libya posix US
            Asia EST Hongkong localtime posixrules UTC
            Atlantic EST5EDT HST MET PRC WET

            Chile GB-Eire Israel NZ Singapore
            CST6CDT GMT Jamaica NZ-CHAT SystemV


            The time zone for EDT is "EST5EDT". The output of TZ="EST5EDT" date as of 10 May 2019 02:11:26 UTC:



            Thu May 9 22:11:26 EDT 2019


            Or use city's name where EDT is used. Examples: America/Kentucky/Louisville, America/Kentucky/Monticello, America/New_York, Canada/Eastern, etc.
