DateTimeInput calendar start day

A fellow countryman asked this question before. The answer is that the component doesn't support it but some magic can be applied and Victor supplied an answer that seemed to work.

Datetime picker - change first day of the week?

Is there a way to change the first day of the week for the datetime picker in perspective? In Sweden it’s unsusal to put Sunday as the first day of the week and I can’t seem to find a way to change it.
