Deprecation error in server_time method

I am getting the following error now that I have upgraded to resque 1.27.1:

```Passing 'time' command to redis as is; blind passthrough has been deprecated and will be removed in redis-namespace 2.0 (at /usr/local/bundle/gems/resque-1.27.1/lib/resque/data_store.rb:94:in `server_time')```
