[GRASS-user] t.rast.list use

[Sören Gebbert]

Hi Veronica,
sorry for the late response.

You can use the datetime[1] functionality of sqlite to perform this
task, this should work for Jannuary:

t.rast.list input=cla_null_mayor65 where='start_time >=
datetime(start_time, "start of year") and start_time <=
datetime(start_time, "start of year", "1 month")'

Best regards
Soeren
