Re: [netcdf-java] Troubles having different Time dimension names on different forecasts

Hi list.
Sorry for bothering you again. (I know how much can be annoying receiving
"PING" from the same user about same Topic within a mailing list since I
also contribute to some open source projects where people frequently repeat
asks for help to devs which are basically volunteers).

Did you have any chance to take a look to my latest question?
No rush on this since I'll be in vacation next week. I just would like to
know if somebody has any feedback or idea on that.

Best Regards,
Daniele
