Time Zone for Time-Settings / Curfew

We are located in Australia (GMT +10)

Norton Family premium reports my son logging in during curfew at 6:47am.  This appears to have been for a curfew warning at 16:30 (local time).  We don't have a restriction set up for that time, so I can only assume that Norton Family is using the web-specified settings but applying some other time zone (US perhaps?)

I assume there are regional settings in the Norton Family profile to fix date/time reporting and limits, but have not been able to find them in the web portal.

 

FURTHER UDATE:

He just signed in at 8:53am (Local time) -- this should be permitted.

Norton Family has just reported a curfew violation at 10:52pm.  It does indeed seem that the regional settings are incorrect, and need changing.  Where in my profile can I do this?
