That's correct.

I suspect a bad system clock.  I know that the radar sites do have
more than one clock.  Perhaps the good clock is used for the filename
and the bad system clock is used for the data-product creation-time.

It's quite likely that clock problems are the cause of data-product
"gaps".  Running old versions of the LDM can also contribute.
