[GRASS-dev] Invalid timestamp file for raster

[Veronica Andreo]

Hi Nikos,

Have you tried with t.register?

You would need to set the start_time="2013-04-13 10:00:09.935626" plus an
increment="10 seconds". I have not tested, but it should work.

I think it's better than r.timestamp if you want to create time series,
even though it would be great to fix the bug in r.timestamp, anyway.

Cheers,
Vero

The following do work:

>> 13 Apr 2013 10:00:19.935626

Obviously.

Here a quick test for 0x:

function seconds { printf "%02d" $1; }
for SEC in `seq 0 1 59` ;do echo $(seconds $SEC) && r.timestamp B1 date="13
apr 2013 10:00:$(seconds $SEC).935626" && r.timestamp B1 ;done
