"Dates" issue with US settings versus Dutch settings

Ok so my windows has Dutch regional settings, some of my colleagues have US settings.
Following should work in either situation.

Please see excel attached.
There is a column (A) with date time and AM/PM CET setup.

I need to lose the CET (with replace that is easy) so excel will see the field as a normal date field.

However after this (see column D) the lines with Feb nicely go to a "8-2-2019" format, however for me the line with 11-Mar-2019 will not convert as month 3 would not be Mar but Mrt in my settings.

How can I get this to work without regional settings being an issue?
Thanks.
