Yes, GrADS requires a linear time axis with a constant interval between time steps. The only workaround I can think of is to break up your file into pieces, one time step per file, with a naming convention that contains sufficient information about the date associated with your file so that you can use templating. Then create a descriptor file with the daily time axis increment and enough time steps to cover the entire period to span your data, and then GrADS will populate the time steps where your data files exist and treat the rest as missing data.

I’ve checked my netcdf file with Panoply: this interface correctly handles the time coordinate. For instance, if i set t=100, Panoply displays the 100th field record and the corresponding time.
I’m missing some basic understanding of Grads: should the time coordinate be evenly distributed?
Thanks for any tip -gilles
