Fixed failing spec on create method

I got a failing spec on create method:

::create
  - create object with hash
2013-09-08 10:45:34 +0530
 [✗] This test has not passed: FAILED - 2013-09-08 10:45:34 +0530.==(2013-09-08 10:45:34 +0530) failed! 
 [FAILED - 2013-09-08 10:45:34 +0530.==(2013-09-08 10:45:34 +0530) failed]

	spec.rb:690:in `satisfy:': ::create - create object with hash

	spec.rb:439:in `execute_block'

Added a fix to the spec, basically time objects comparison leads to failures, so converted that into string.
