how to set time zone for mongoid
===

I am using mongoid for my rails app.

I want to set time zone for mongoid.

I tried with this in application.rb

    config.mongoid.time_zone  = 'Kolkata'

but no luck. I also tried with this

    use_utc: false
    use_activesupport_time_zone: true

still it uses default time zone UTC.

rails 3.0.10

mongoid 2.2.4

please help.

thanks in advance.
