Hi,
I found the problem! It works very well now. The problem is, I think, didn't
compile with the proper gdbm library for weather. Now using the version 1.7.3
everything works very well as expected.
FYI, the default_time = l12 means to search for the latest obs in the last 12h
A default_time of 12 would mean to display all 12 hours of obs.
Thanks four your help, it helped me to pinpoint rapidly the problem by
elimination...
