I'm hoping somebody can remind me of the proper time-synching of PRI, SEC, HK, and lro_spice files.

As I recall, the primary science packets are tagged with the time of the second in which they are *sent*, meaning that the data were actually recorded during the prior second.  So to properly compare with secondary science to get the configuration of the instrument, you need to compare the primary science data from second "n" to the secondary science from second "n-1".

Is this time shift accounted for in the L2 files? Or do I need to do that myself?

Does the same shift need to happen with the lro_spice files and housekeeping files?
