Adrian Hunter e39a12cbd2 perf tests: Add a test for time-utils 
Test time ranges work as expected.

Committer testing:

  $ perf test "time utils"
  59: time utils                                            : Ok
  $ perf test -v "time utils"
  59: time utils                                            :
