Hi @whitciv,
Could you please share a bit more about your scenario?
Do you want your users to select a time value rather than type manually within your app?
Based on the needs that you mentioned, I think the Dropdown controls could achieve your needs.
I have made a test on my side, please take a try with the following workaround:


Set the OnVisible property of the screen which contains the Time entry input box to following:
Set(SelectedTime, Blank())
Set the Default property of the Text Input box (Time Input box) to following:
If(!IsBlank(SelectedTime), SelectedTime, Text(Now(), DateTimeFormat.ShortTime))
Set the Items property of the HourDropdown box to following:
["00","01","02","03","04","05","06","07","08","09","10","11","12","13","14","15","16","17","18","19","20","21","22","23"]
Set the OnChange property of the HourDropdown box to following:
Set(SelectedTime, Time(Value(HourDropdown.Selected.Value),Value(MinuteDropdown.Selected.Value),0))
Set the Items property of the MinuteDropdown box to following:
["00","01","02","03","04","05","06","07","08","09","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24","25","26","27","28","29","30","31","32","33","34","35","36","37","38","39","40","41","42","43","44","45","46","47","48","49","50","51","52","53","54","55","56","57","58","59"]
Set the OnChange property of the MinuteDropdown box to following:
Set(SelectedTime, Time(Value(HourDropdown.Selected.Value),Value(MinuteDropdown.Selected.Value),0))
