24h time and european date format

[Maarten]

When I change the language to Nederlands the date/time is displayed as d-m-yy H:mm:ss.

Great! I'd have expected that.

Still not according to Windows' settings.

Why?

Because windows settings is d-M-yyyy (4 digit year).

And I like to see programs in English because I have an English Windows installation, so it is a little bother for me.

I don't get that: you're Dutch but you want to see the program in English? Why don't you change the language to English then?

Because then I have a time format that I don't like and which takes me time to read.

The key thing is: windows has date and time format settings. These are independent from the language of the windows installation. Even within the localization you have more than one choise. My localization is Dutch (Netherlands), but I can still choose from 7 different date formats.
I would have expected that a program takes these date and time settings and uses them. That's what other programs like spreadsheets do.
What else is the use of making a system wide date and time format if the programs you run do not use it?
