[FOSS-GPS] http/ftp configuration time downloading mask

[Jean-Michel Pouré]

Dear Friends,

What is the meaning of "T" in rtklib configuration file:

inpstr3-path       =
anonymous:user@@cddis.gsfc.nasa.gov/gps/products/%W/igu%W%D_%hb.sp3.Z::
T=-10800,21600,10800,600

Example: T=-10800,21600,10800,600

-10800 ***could*** mean "look for a file 3 hours before", but I don't
understand the syntax.

Any help appreciated. I am willing to download ephemerides from
rgpdata: ftp://rgpdata.ign.fr/pub/products/ephemerides
and would like to find the right time mask.

Kind regards,
Jean-Michel
