Hi, 

 Could you please share what is the exact scenario you want to achieve?

I do not understand this sentence: I can choose the time on my computer, but I can't choose the time on other computers. How do you want to choose the time on other computer?

DateTimePicker documentation: 
All properties datetime picker provides are described in the documentation: https://docs.telerik.com/devtools/xamarin/controls/datetimepicker/datetime-picker-overview

[li]

I need two time controls, a start time and an end time. When I use this control, clicking this control will not pop up the selection time box. In the past, I can select the time locally. Other computers use my page and the select time box will not pop up. Now it's not even local. Click the control and the time selection box will not pop up

Hi, 

Regarding this: When I use this control, clicking this control will not pop up the selection time box. - on my side the popup opens when I click on the DateTimePicker. 

Next Steps: Please open a support ticket and attach sample repro project. I am not sure I understood the issue you have with the DateTimePicker control. Also attach a video of the behavior and add a step to reproduce the issue.

Additional info: In general, you can select time from the date time picker. For example, you can use the datetime picker in time mode when setting the DisplayStringFormat="HH:mm:ss". Here is an example: 
https://docs.telerik.com/devtools/xamarin/controls/datetimepicker/datetime-picker-key-features#time-picker-mode 

The popup displays only time spinners. and you can select time. If you want to add a date range here are the properties you can use https://docs.telerik.com/devtools/xamarin/controls/datetimepicker/datetime-picker-key-features#date-range
