[Paraview] csv point data through time

[andrealphus]

I have a database of earthquakes in a csv file formatted as;

x,y,z,M,time
344914.339004,4153503.07632,-7703,1.22,441772084.24
337090.052527,4158668.87752,-10404,1.06,441774936.69
335085.941364,4156934.63971,-7245,0.72,441789441.37
337111.336138,4167120.16812,-8539,0.76,441790442.57
335024.848735,4159463.38774,-4032,0.71,441801083.1
338135.588075,4159856.10709,-4160,1.17,441821076.16

where time is in unix seconds.

Normally I plot this by table_to_points, as spherical glpyhs, colored
by time and sized by "M" (magnitude), see image;

But it would be nice to step through these points with time. I just
cant figure out how to actually get paraview to recognize my time
column in my table (or my point attribute).

Normally I would either reformat this to a netcdf or create individual
file at each time step, but for this case these are not suitable
options.

Any suggestions?
