# Sets <tt>Time.zone</tt> to a TimeZone object for the current request/thread.
#
# This method accepts any of the following:
#
# * A Rails TimeZone object.
# * An identifier for a Rails TimeZone object (e.g., "Eastern Time (US & Canada)", <tt>-5.hours</tt>).
# * A TZInfo::Timezone object.
# * An identifier for a TZInfo::Timezone object (e.g., "America/New_York").
#
# Here's an example of how you might set <tt>Time.zone</tt> on a per request basis -- <tt>current_user.time_zone</tt>
# just needs to return a string identifying the user's preferred TimeZone:
#
# class ApplicationController < ActionController::Base
# before_filter :set_time_zone
#
# def set_time_zone
# Time.zone = current_user.time_zone
# end
# end
def zone=(time_zone)

end
# Allows override of <tt>Time.zone</tt> locally inside supplied block; resets <tt>Time.zone</tt> to existing value when done.

# Time.utc(2000).in_time_zone # => Fri, 31 Dec 1999 14:00:00 HST -10:00
#
# This method is similar to Time#localtime, except that it uses <tt>Time.zone</tt> as the local zone
# instead of the operating system's time zone.
#
# You can also pass in a TimeZone instance or string that identifies a TimeZone as an argument,
# and the conversion will be based on that zone instead of <tt>Time.zone</tt>.
#
# Time.utc(2000).in_time_zone('Alaska') # => Fri, 31 Dec 1999 15:00:00 AKST -09:00
