It has to be something to do with my environment as Phillip Halstrom above has the same version of ruby and has a good result.... I hate to rebuild my mac for such a lame issue but I am starting to think about it or to move this project to a vm. What is weird is this: I am poking around active_support/core_ext/date_time/calculations.rb and see the methods such as #since, #advance, #past?, etc. available, yet I am getting an error doing what Michael Pavling suggested above, as well as 'no method found' on the other methods: ruby-1.8.7-p334 :003 > DateTime.now.since(1.day) NoMethodError: undefined method `since' for #<DateTime 2011-04-19T12:09:42-05:00 Then I decided to check the methods for DateTime.now, in my bad ruby 1.8.7-p334 / rails 3.0.7, vs my working ruby 1.9.2-p136 / rails 3.0.3. As you see on the gist below the list of methods are very different. I am wondering if there is a disconnect in how rails is loading in my 1.8.7 -- because at initial glance, it looks to me like the DateTime class I am looking at in active_support is not being loaded as the methods it specifies are not there. Following are outputs of the methods for DateTime::now for my 1.8.7/Rails 3.0.7 and 1.9.2/Rails 3.0.3: https://gist.github.com/928958 So, if anyone has made it this far, I guess my next question would be as to how I can confirm whether active support (in particular the file mentioned above is getting loaded). Actually if Phillip, or someone else (running Ruby 1.8.7-p334 and Rails 3.0.7 ideally on Snow Leopard mac or close) to this set up can send me their output of DateTime.now.methods.sort, it would at least confirm things.
