I was looking at the Expression shared in the screenshot and I believe it should be HH:mm, rather than HH:MM, as the capital M looks at the month, rather than the minutes. more info. here: Moment.
then, to apply this to the time zone you mentioned you can replace the EST with AET.
I would start by displaying a message with the time (HH:mm) format every second:
once you can confirm that it’s outputting the message as you’d expect, you can change the Expression in the If statement with the 2 changes (lower case Ms and AET).
could you try that and let us know how it goes?? thanks!!
