  Log:
  Add a check for wtmp records which have invalid values for ut_time.  Wtmp
  records with time==0 get "the time of the last valid record", while records
  where time goes backwards (compared to the previous record) are skipped.
  Also prints a message saying how many records were changed or skipped due
  to these checks. Check was inspired by a simpler check in OpenBSD's version.
  
  This is all meant to sidestep problems that Tillman Hodgson noticed with 'ac'
  when running sparc64 with 64-bit time_t's.  The real problem is whatever is
  creating wtmp records with ut_time==0, of course, but I have not yet figured
  out what is doing that.
