[IDV #RMI-290185]: Problems of grads ctl file time?

Jian,

Sorry about that. I gave you a Java 8 program instead of a Java 7 program which
is why my little test failed to run, and therefore revealed no useful diagnostic
information.

But at any rate, you were able to solve the date problem with the instructions
below. Is that true??

Are there any outstanding issues?

Best,

Unidata IDV Support
