Bug? DateUtils - Crash when 24-Hour time turned off

[Andrew (Digitwell)]

I have the following lines of code.

    Private dy,mt,yr As Int
    dy = DateTime.GetDayOfMonth(DateTime.Now)
    mt = DateTime.GetMonth(DateTime.Now)
    yr = DateTime.GetYear(DateTime.Now)
    calrng.RangeStart = DateUtils.SetDate(yr,mt,dy)

This code works perfectly if in
Settings -> General -> Date & Time -> 24-Hour Time is turned on

If you turn if off I get a crash on the SetDate

Spoiler: Crash log

A bit more information,

If I set the phones region to US then all is fine.

I also found this: https://developer.apple.com/library/archive/qa/qa1480/_index.html#//apple_ref/doc/uid/DTS40009878

Is it possible to set the locale on iOS programmatically?
