QB Issue Resolution:
This appears to have been a system-wide problem with the Keypay system that is being fixed now. Specifically, the Keypay system was doing validity checks against UTC time instead of AEST.
For part of each day, UTC and AEST time zones are on different dates, which was causing the system to produce this error message when doing validity checks. During a normal Australian workday at this time of year, this error would only be appearing for users who attempt to lodge with the ATO prior to 10:00am AEST. This could be why nobody has reported it before now.
I successfully lodged it with the ATO a few minutes ago.
Both UTC and AEST are on the same date right now, but Support indicated that the problem would be fixed before it can happen again at midnight AEST tonight.
