This will come in time through natural play. However, if you want to speed up the process, choose Survival mode. Both rewinding and fast forwarding time count for this achievement. There is no limit to the amount of fast forward you can use, so you can abuse it. Hold down whilst playing, only slowing down if something big will get past you. If you die, select retry and do the same thing. There is no way to keep track of how long you have traveled through time, unfortunately. Be patient and it will come.
