I'd like to suggest that the exported data is time aligned on each row of the CSV file. The data could be timestamped to the same time instead of having each column associated with its own timeline.
Currently:
-23.02463412,404710,-4.026059151,401801,
-22.02457714,404711,-3.025449038,401802,
-21.02476311,404712,-2.025968075,401803,
-20.02499318,404713,-1.025913,401804,
-19.02466822,404714,-0.02559709549,401805,

My suggestion:
-29.02470112,404704,-29.02562118,401776,
-28.02465701,404705,-28.02558303,401777,

-26.02516603,404707,-26.02607512,401779,
