RBR850 not adjusting daylight savings time for Australia / Adelaide timezone

Settings under Administration > NTP Settings.  Doesn't matter which NTP server is being used.

Works and adjusts DST correctly for the Brisbane / Sydney / Melbourne timezone and others work correctly.

The router doesn't seem to know that the Adelaide / Darwin (GMT+930) timezone also has a daylight savings time that should be applied.

    Wondering if thats due to the 30 minute off set time for the region select? 

    Had this been working before? 


    Checking my RBR850, Selecting Adelaide and selecting and un checking the DST box, doesn't change the time at all. Selecting Brisbane...selecting and unchecking the DST box does change the time by an hour. 

     

    What FW version do you have on the RBR?

      Couldn't say - haven't had it that long so this is the first DST changeover.  Agree that it might be the weirdness of the 30min off set timezone...

      FW version is V7.2.8.5_5.1.21

        (and hadn't really noticed the time not being right more generally - that said, might be the updated FW as that was updated recently)

    What is the time difference between Australia / Adelaide and Brisbane / Sydney / Melbourne? Is it only 30 minutes difference or something more then that?
