You can simply run "rake time: zones: all" in your shell, you will find all the timestamps displayed for use in Rails. From the above, you can easily find the INDIAN time zone, as shown below.
* UTC +05:30 * Chennai Kolkata Mumbai New Delhi
Put any of the above names in config/application.rb
as follows:
config.time_zone = 'Chennai'
Just restart the server and you will find the updated time zone.
Thanks.
