      for minute = 1, 30 do

     end
end

The file will error but also output a lexical error, likely from the analysis.

TimeOfDay is a string that looks sort of like a timestamp. What you wanted is probably SetMinutesAfterMidnight.

That being said, this error message could definitely be improved to tell you that. I’ll file a feature request internally for that.

You could also use ClockTime which is in hours.
