Re: relative times in the IDV; time loops

If you have a netCDF file with data time value and unit such as "250 Myear" the data appears in the IDV but the time label is something like "250001794-10-20 07:29:59Z"

If you do a time animation loop of two or more of these, from one data file per time step, separated by say 50 million years, the odd times do loop in the label, but all displays appear all the time.

Is there some way to not tie the time to the time at the moment, just show "250 Myr," and to make the loop work for each data time in separate files?

If you have one time per file, they will all show up at the
display.  The animation logic needs to find the nearest data
timestep to the animation time step for each display.  If there's
only one time for a particular data object, then that ends up
being closest.

We are thinking about ways to get around this, but this is the
default VisAD animation logic.
