Monitor looks at the value of the key at HKLM\\System\\CurrentControlSet\\Control\\TimeZoneInformation to find what the current time zone is. I would guess it will have a key ‘TimeZoneKeyName’ set to ‘Display’. If you can change the value of 'TimeZoneKeyName' to a valid time zone then that should resolve the error (one way to do this would be to go into "change time and
date settings" under the system clock).
Please do let us know if this resolves the issue or not.
