Can someone please tell me how to set the time and get rid of the chime on a Z2 thanks in advance

You can only change the hours, it's basically an hour +/- offset setting. In a sense you're picking your time zone, if that makes any sense. You can change the volume of the chime or turn it off completely by pressing the MENU button and then pressing SETTINGS on the top right. When the settings menu comes up, it will be on the top left. Inside that menu you can change levels for phone ringer, phone voice, system beep, & guide voice. Hope this helps!

The time is set automatically.
