[Fwd: grb2 index file problem (?)] (fwd)

Hiya Rob,

The gbx index files and the gbx8 index files comes from different versions 
of the grib library, so you must be accessing  both libraries. The 
latest version of the library is grib-8.0.jar, so remove the other grib 
jars in the path. For safty sake, remove all the gbx indexes too, use 
only the gbx8 indexes.

The other problem with the value of time is the units should of been 
changed to hours.

{12967200} secs equals {3602} hours

I'll make the units fix.

Robb...

Hi John -

Attached is a grb2 file.  When we open it in ToolsUI (Viewer), ToolsUI 
generates a grib index file.
Sometimes it generates a gbx and sometimes it generates a gbx8 index file 
(seems like a problem?).

When we dump the "time" value/variable using ToolsUI, we get different time
values depending on which grib index file is created:

1. the gbx index yields:

  int time(time=1);
    :long_name = "forecast time";
    :units = "seconds since 2010-02-16T03:00:00Z";
    :GRIB_orgReferenceTime = "2010-02-16T03:00:00Z";
    :GRIB2_significanceOfRTName = "Start of forecast";
    :_CoordinateAxisType = "Time";

data:

 {12967200}

2. the gbx8 index yields:

  int time(time=1);
    :long_name = "forecast time";
    :units = "seconds since 2010-02-16T03:00:00Z";
    :GRIB_orgReferenceTime = "2010-02-16T03:00:00Z";
    :GRIB2_significanceOfRTName = "Start of forecast";
    :_CoordinateAxisType = "Time";

data:

 {3602}

NOTICE that the time values differ. Any ideas? 
Please help ;-)
