NoMethodError for time_zone_select in form

Question

<%= f.time_zone_select :time_zone, ActiveSupport::TimeZone.us_zones %>

I get this error

NoMethodError in Users # new

Application mapping /views/users/new.html.erb where line # 27 is raised:

Line 27 has the above line. I'm really stuck on this ...
