TzTime thread safe?

Rails
1

The implementation of TzTime uses:

class TzTime
class <<self
attr_accessor :zone

and then recommends doing this:

class ApplicationController < ActionController::Base
around_filter :set_timezone

private
def set_timezone
TzTime.zone = current_user.time_zone
yield
TzTime.reset!
end
end

Won’t this cause problems with concurrent requests for two users with
different timezones?

AFAIK Rails doesn’t do concurrent requests.

Rails is not thread safe. Thats why we have to use mongrel_cluster . I
believe Merb IS threaded if you’re worried about concurrency. It is
also a lot faster!
