I guess I should probably drop my gemset and reinstall and see what happens.... ruby-1.8.7-p330 :001 > DateTime.now => #<DateTime 2011-04-16T04:32:20-05:00> ruby-1.8.7-p330 :002 > DateTime.now + 1.day => #<DateTime 2247-11-05T04:32:27-05:00> > > >> DateTime.now > => Sat, 16 Apr 2011 01:00:29 -0500 > >> DateTime.now + 1.day > => Sun, 17 Apr 2011 01:00:32 -0500 > > >> DateTime.now.since(1.day) > => Sun, 17 Apr 2011 01:00:34 -0500 > > B. > > -- > You received this message because you are subscribed to the Google Groups > "Ruby on Rails: Talk" group. > To post to this group, send email to rubyonrails-talk@googlegroups.com. > To unsubscribe from this group, send email to > rubyonrails-talk+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/rubyonrails-talk?hl=en. > -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
