[gradsusr] gadsdf: Time unit has too small an increment (min. 1 minute).

[Jennifer Adams]

I don't know what CDO does to does to the time metadata with the  
yseasave command, but GrADS obviously doesn't like it. I would try  
using xdfopen with a full TDEF statement to override the metadata in  
the file. If that doesn't work, please send the output from 'ncdump - 
c', your xdf-style descriptor, and the GrADS session with any error  
messages.
