Correct me if I'm wrong, but I'm under the belief that a daily bar should end and print (via the run function) at 5:00 PM EST. A new daily bar begins at the same time, which is the open of Sydney. Daily bars never overlap the weekend.

When running Zorro against my Oanda demo account, the bar seems to print 2 hours later. Does this seem incorrect to you guys?

Is the solution to simply use BarOffset?

I think that by default, Zorro begins/ends a daily bar at midnight UTC. Different brokers can change their daily bars at different times however.

You can set Zorro up to change daily bars at any time you prefer. I like the FrameOffset and TimeFrame variables with the frameSync() function for achieving this.
