Ouch. What happened to the database? Do you understand the way
compression works on data?

The first longword is the number of days since 17 November 1858.
(That's a long story). The second word is the number of clunks since
midnight of that day. A clunk is the smallest fraction of a day that
allows a whole day to be represented by a longword. 10's of
microseconds, I think, though I'm not sure.
