Evan, What I said in my previous email needs clarification. The time discrepancy is between your system's clock and the clock where the data-products are created rather than between your clock and the clock on idd.unidata.ucar.edu. It turns out that some of the radar sites have bad clocks, resulting in the log messages that you see. I'm going to notify the NWS about the offending clocks. Hopefully, they'll synchronize them and the number of such messages will decrease.
