grib2ctl.pl problem

[Wesley Ebisuzaki]

All,

   I thought about adding minutes to g2ctl and it wasn't hard.  Mike 
Masscotte did
the testing because I didn't have any realistic samples.

Litta,

     grib2ctl doesn't minute time steps.  The only way is to try to 
modify the TDEF
statement as you have attempted.  Your attempt may have failed because 
of a space between
30 and mn. It could have also failed because the TDEF has a starting 
time 00Z11may2009
where your file may have started NN minutes after the hour.  
(00:NNZ11may2009).
You should use the gribmap -v option to check for matches.

    I have no plans to add minutes to grib2ctl because grib2 is 
replacing grib1.  I'll
think of adding minutes to g2ctl.
