Thank you for contacting us.
I am afraid we don't support such feature. By default when you input 2, for example, the RadTimePicker gets this as 2:00 , not 14:00. You can add a specific Culture to define time format.
You can also handle SelectedTimeChanged event and to implement your own custom logic that suits your needs.
I hope this information helps. I will be glad to assist you further.

Thank you for getting back to us.
Please, check your regional and time setting for the OS. Also, you could try to set culture for time format. If this could not help you, please send us a sample project that reproduces the issue you have with RadTimePicker.
I hope this helps. I will be glad to assist you further.

We have discovered that the dateTime Picker fails when we use the New Zealand regional settings. This causes the time to set to AM. This is a problem on XP and Win Server 2003 but not a problem a Mac (finally a reason to have a Mac).
Please review the attached screen shot showing the format differences between New Zealand and US setting. Please note that we cannot ask our users to change their settings just to accommadate our application.
Please let me know the outcome. Not sure if you want to change your code for a tinpot island on the other side of the world.

Thank you for contacting us.
Attached you can find a sample running project with set Culture to English (New Zealand) and it should work fine. Please, test it and let me know if this helps you. If not, please try our latest controls from the Q2 release.
You can try also our new RadDateTimePicker control that can be used as DatePicker, TimePicker or both.
Please, let me know if this helps you. I will be glad to assist you further.

1. Original time for control1 is 9:00 AM (same time for control2).
2. Select new time (1:00 PM) for control1, control2 displays 1:00 PM too.
3. Go to control2 to try to select another time. Upon clicking on control2, its time changes from 1:00 PM to 1:00 AM.
Notes:
a. First, it triggers control2's ParseDateTimeValue event, and the following would be the values:
args.TextToParse = <date> 1:00 PM
args.Result = <date> 1:00 AM
control 2's ToolTipContent property = <date> 1:00 AM
control 2's SelectedValue property = null
b. Second, it goes to control2's SelectionChanged event,
e.AddedItems[0] = <date> 1:00 AM
e.RemovedItems has no items
c. Then, after control2's SelectionChanged event, the ParseDateTimeValue event is called again.
args.TextToParse = <date> 1:00 PM
args.Result = <date> 1:00 AM
control 2's ToolTipContent property = <date> 1:00 AM
control 2's SelectedValue property = <date> 1:00 AM
Thank you for getting back to us.
Could you please send us a running sample that reproduces the problem. It would be very helpful to investigate the problem.
I will be glad to assist you further.

Unfortunately, I could not find the problem in your code as long as I am not able to run and/or debug it. I made a sample running project keeping the main logic and try to reproduce the problem, but to no avail. Attached you can find the sample.
Please, let me know if you have the same problem with this sample and if you do - tell me the steps to reproduce it. Feel free to modify the project to reproduce the issue. That will help me a lot.
Looking forward to your reply. I will be glad to assist you further.

Thanks for checking it out. I don't see any attachment in your reply. Anyway, I checked again my sample project and I still see the problem. See the attached images for the steps i made.
Thanks!

Please accept my apologies for the missing attachment. Please check the example. I suggest you to implement your logic in the ViewModel.
