To reproduce, Set app locale to a right-to-left language (fa for example) then open timepicker.

Besides that "Select Time" which not translated, Why is that the time of day format is in mm:hh format instead of hh:mm?

RTL doesn't mean everything should be written right to left, Those languages still use hh:mm for time format.
Also it wasn't an issue in previous TimePicker widget.
