The reason I was doing the offset hack was because I was trying to get 1.8 and 1.9/2.0 to be consistent with regards to printing the time zone using `%z` in `strftime`. If we use `inspect`, we have to work around the issue in our tests that the string returned will be different depending on the version of Ruby.

```ruby
2.0.0p247 :001 > Time.now.inspect
 => "2013-10-06 21:20:31 -0400" 
```
```ruby
1.8.7 :009 > Time.now.inspect
 => "Sun Oct 06 21:20:22 -0400 2013" 
```
