Hi,  
added following line after listening to one of the railscasts on  
formatting date and time:  
Time::DATE\_FORMATS[:due\_time] = “%I:%M %p”

Now i am adding a new column to one of my tables in the database and  
rails is giving following error:  
/var/www/html/myapp/pms080204/config/environment.rb:59: uninitialized  
constant Time::DATE\_FORMATS (NameError)

Please help.  
Thanks.
