If you don't know what a timeslip is, watch this about three soldiers on patrol who suddenly found themselves in the town they needed to be, but at a seemingly totally different moment in time. One such event may be an anomaly, but on the timeslip acrosstic page you will find a few more examples in the video.

Only in the present do we find the true presents of life! And yes, that was something I learned the hard way too...
