Macro to Change System Date format?

is it possible to create a macro that would be able to change the system date format of computer it is running on?

Noted. Any way you could enlighten me on how?

Sure, I have a workbook that goes to our workers, this workbook sends an automated text file in an email. This text file is then picked up and imported into an online "app". When the local time settings aren't USA it imports the wrong dates and messes it up. Our workers aren't always the same people and often use different computers (day shift and night shift). The easiest solution is to have all the local dates the same so it is consistent to the importing program. I will PM you login details to our online app so you can see real-world what it does.
