[gradsusr] different Z stamp on daily mean data?

[Muthuvel Chelliah - NOAA Federal]

Hello experts,

I have two daily mean grib2 data sets, but one has daily stamp at 00Z and
another at 18Z. I want to refer to them by only their daily stamp in Grads,
so I
can difference them or correlate them, etc.. Is that possible? How can
I do that? As such it is not allowing me to do that.

Thanks
Muthu
