How to configure rails to serialize datetime to json always in utc?

Question

Is it possible to configure rails to serialize datetime to json always in utc without timezone?

For example: instead "2011-06-15T21:40:05+06:00" i want "2011-06-15T15:40:05+00:00"

Answer 1

To set the time zone for the entire application add this line to environment.rb

config.time_zone = 'UTC'

To set the time-zone before a render call

Time.zone = 'UTC'    
render
