What exactly does you script do ?

Does that mean that each line represents one raster with one non-null 
pixel ? If yes, then I don't see much else then iterating over the file, 
using something like r.in.xyz to import each line as a raster and in 
parallel writing a text file with the map name and start time. This file 
can then be fed to t.register to register all the files into a 
space-time dataset. AFAIK, the temporal modules do not directly handle 
import & export of data (except for space-time datasets exported from 
GRASS).
