Regional settings plays a very vital role as the SharePoint
has been extensively used all over the world with different languages.
So many requirements can arise such as:
-How can we set the default regional settings for the new site
collections?
-How can we change the default regional settings once the site
collection created?
-How can we change the default time zone?
-How can we change the default calendar?
-How can we set the alternate calendar?
-How can we change the time format? 12 hour/24 hour?
Primarily we are going to focus as how we can change
the regional settings in central administration as well as at the site level.
