  Use time tolerance in run_code_generation check.
  
  The mtime values I was seeing on my file system were sometimes
  floating point numbers that were very very close but not exactly
  the same. This might be due to numerical errors. Increasing the
  tolerance to something still very small, precision is less than
  a second. It will lead to fewer rebuilds of non-dirty files.
