What is the time zone used in the Filing Manager interface?

Unless time zone is stated explicitly in the interface, it defaults to your computer's time zone.

e.g.
'Submitted On' will default to your computer time zone.

If ASIC rejected filing due to late lodgement, 'Submission message' will include time zone info: "The report has been lodged after the T+3 9am due date (AEST)."
