How to set Date and Time using Time Server

My computer is an old one.  Now the battery in the motherboard is not keeping the system date and time properly.  So I need to set date and time every time before browsing the internet.
While searching I got a very good answer to my query.

w32tm /config /update

w32tm /resync /force

 Then configure schedule to execute the script
