 Even then you may experience intermittent issues though, because the clock of the Identity Provider may drift slightly ahead of your system clocks. To allow for a small amount of clock drift you can initialize the response passing in an option named `:allowed_clock_drift`. Its value must be given in a number (and/or fraction) of seconds. The value given is added to the current time at which the response is validated before it's tested against the `NotBefore` assertion. For example:
 
 ```ruby
-response = OneLogin::RubySaml::Response.new(params[:SAMLResponse], :allowed_clock_drift => 1)
+response = OneLogin::RubySaml::Response.new(params[:SAMLResponse], :allowed_clock_drift => 1.second)
 ```
 
 Make sure to keep the value as comfortably small as possible to keep security risks to a minimum.
