Need help for windows script

I am new here. We are on our deployment phase of new pc's and my manager just asked if i can create a script that change the time zone. Means i login using any user name and run this script, this script gives me option like user is in Central time zone or eastern time zone (means mentions all timezone) like in radio buttons and if i select EASTer time zone it and run the script, it changes the time as EASTERN.
 
Can please somone help me? I will really appreciate your help. Thank you.

Which script is "this script"? Is it a script? What language is it written in? What is the code?

I am looking for the script, which can change the timezone and ask for different zones like Eastern or Central and lets say if select US Eastern time, script changs the time accordinly.
 
Can someone help to create this script?
 
Thank you!

Aaah...I understand now. What language would you like to write this script in?
