Date and time picker customformat

[Nuz]

I'd like to switch between various date formats displayed on date and time picker control.
I'd like to display the month of the day as "written" according to country the user has selected. For example, the selected country is UK -> the date 31/12/2011 should be displayed as "31 December 2011". If the country is Norway, the date should show as "31 Desember 2011" and so on.

How can I define the customformat property to do this?

I actually figured this out with using the callback fields for custom formatting.

I just don't understand why the control doesn't align the date to left. My custom formatting is

"XXXX dd, yyyy"

and the array containing the months is defined as:

sEnglishMonths(0) = "January"
    sEnglishMonths(1) = "February"
    sEnglishMonths(2) = "March"
    sEnglishMonths(3) = "April"
    sEnglishMonths(4) = "May"
    sEnglishMonths(5) = "June"
    sEnglishMonths(6) = "July"
    sEnglishMonths(7) = "August"
    sEnglishMonths(8) = "September"
    sEnglishMonths(9) = "October"
    sEnglishMonths(10) = "November"
    sEnglishMonths(11) = "December"

Instead of having the date displayed nicely left-aligned as "December 31, 2011" the date is now full of blank spaces and very badly aligned:

How can I adjust it?
