Language of variable in ${VM_DATE}

Hi all,
I’m looking for a way to change the date passed by the ${VM_DATE}-variable from English to another language. The body of my e-mail has already been changed to Dutch.
Can anybody advise me on how to do this?
Your help is appreciated!

Can I join to you research?:?:
I find on Internet that the data from the ${VM_DATE}-variable came from the library of C++ time.h :bulb:
I want to change the language to Spanish. :exclamation:
Best Regard.
