Multiple NetCDFs With Different Epochs



I'm cross-posting this to the DODS tech and LAS users lists for maximum
coverage -- sorry if you're receiving this twice or thrice.

I have a bunch of netCDF files that comprise a time series, but the
netCDF files have different epochs. Can Ferret "normalize" these netCDFs
when doing a time series plot or display?

I want to use the DODS Aggregation Server on these netCDF files, and I
think that the DODS AS is taking the epoch from the first netCDF file
listed in the catalog and using it for all the rest, thus offsetting the
time slices for those netCDF files with a different epoch. (Considering
that the aggregate can have only one epoch reasonably defined for it I'd
do the same thing, of course.)

In terms of "best practices," DODS AS, Ferret, and (or) other software,
does this situation pose an insurmountable temporal jumble, or is it
merely a tolerable nuisance? I'd like to convince my data provider to
stop using multiple epochs, so I'm hoping to hear others' opinions on
this.

Thanks,

Mark
