How to format \today to DD-MMM-YYYY format?

Question

Anyone know how to format \today to DD-MMM-YYYY format? (Example 01-JAN-2017). Note that it is important that the month is in capital letters.

I've tried some available packages, but so far haven't been able to find a solution that works.

Anyone?
