The first column is MJD.  The second column is seconds within that day.
(I chopped off the right end to avoid line wrap.)

It took me a while to figure out what was going on.  I got confused when 
didn't see anything interesting at midnight.

23:59:46 is 14 seconds early.  I guess they inserted the leap second at 
midnight GPS time rather than midnight UTC.
