Can whenever take timezone from config?

Currently when we write cron jobs using whenever application (rails) timezone is not considered?

For ex. If in config/application.rb I write

config.time_zone = 'Asia/Kolkata'

and in scheduler

every :day, :at => '09:30am' do
  rake "leave_reminder:daily"
end

It is written as it is to cron. My application timezone is different than server and I don't want to change time zone of my server. So when I write cron job I need to change time to server's time zone.

Can we consider server's and applications timezone and convert accordingly so each time people don't have to worry about timezone?
