Thanks everyone--sorry been extra busy for a while just now seeing all the responses. Here is a sample of my data:

119.51.47 36.22.67
119.51.34 36.24.23
119.51.23 36.23.08
119.51.47 36.24.83
119.57.07 36.30.58
119.57.50 36.30.58
119.42.05 36.29.36
119.40.30 36.28.88
119.52.44 36.28.91
119.51.90 36.29.11
119.52.45 36.29.22
119.51.89 36.28.67
119.51.25 36.28.69
119.51.69 36.29.18
119.58.20 36.32.47
119.58.12 36.32.45

It doesn't look like the last data is "seconds" (over 60) so I am guessing it is decimal minutes.
