.net How to show time in correct format?

I have a VSTO Outlook add-in. This add-in shows winforms window with DateTimePicker contorl, it is used to choose time of day. I want to set time format similar to current Windows time format (like in clock from taskbar).
To do this I use following code:

this.dateTimePicker1.Format = DateTimePickerFormat.Custom;
this.dateTimePicker1.CustomFormat = System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.ShortTimePattern;

In Windows Region and Language settings I have French in Format and Location and English in Keyboards and Languages.
As a result, in my form I see 7:00 instead of 19:00.
CurrentCulture, CurrentUICulture and InstalledUICulture returns "h:mm tt" shorttime format and culture name is en-US.
My question is how to determine that Windows shows time in French format (HH:mm) and show time in DateTimePicker in this format?

--edit
When I run following code in separate console application

Console.WriteLine(CultureInfo.CurrentCulture.DateTimeFormat.ShortTimePattern); 
Console.WriteLine(CultureInfo.CurrentCulture.DateTimeFormat.LongTimePattern); 
Console.WriteLine(CultureInfo.CurrentCulture.DateTimeFormat.FullDateTimePattern);

it returns
HH:mm
HH:mm:ss
dddd d MMMM yyyy HH:mm:ss

In Outlook add-in similar code returns american format:

h:mm tt
h:mm:ss tt
dddd, MMMM dd, yyyy h:mm:ss tt

Outlook is setup to use default Windows language (English).

To get time in Windows format, show form in separate thread. When showing it in Outlook thread it takes Outlook culture settings.

Rather than using custom formats, can't you use..

this.dateTimePicker1.Format = System.Windows.Forms.DateTimePickerFormat.Time;

This should show the time in the correct format (i.e. the one selected by the user)

What do you get if you run the following? 

Console.WriteLine(CultureInfo.CurrentCulture.DateTimeFormat.ShortTimePattern);
Console.WriteLine(CultureInfo.CurrentCulture.DateTimeFormat.LongTimePattern);
Console.WriteLine(CultureInfo.CurrentCulture.DateTimeFormat.FullDateTimePattern);

With my 'region and language' region set to 'French (France)' I get this.

HH:mm
HH:mm:ss
dddd d MMMM yyyy HH:mm:ss
