  We report a long-term (1961-2017) study of the eclipse times in the dwarf
nova WZ Sagittae, in an effort to learn its rate of orbital-period change. Some
wiggles with a time scale of 20-50 years are apparent, and a connection with
the 23-year interval between dwarf-nova eruptions is possible. These
back-and-forth wiggles dominate the O-C diagram, and prevent a secure
measurement of the steady rate of orbital-period change.
  The line, it is drawn, the curse, it is cast.
  The slow one now will later be fast...
  For the times, they are a-changin'.
  - Dylan (1963)
