python - File in folder created before folder itself -


i have got interesting behavior while reading folder , file in folder creation times. explain this?

creating folder

os.makedirs(version_dir+test_name)

running sub-process in folder , create result file there

err_code = common.run_proc(common.get_root_dir() + test_name, custom_path_str=version_dir+test_name)

then there script read creation time of folder , result file using os.get.getmtime , apparently creation (as understood docs modification time) time of file within folder 1403197510.1 , folder 1403197510.19.
so basicly have created file in not existing folder. how work or why have such strange output?

what believe seeing fact windows modify folders represent files within.

so happens:

  • os.makedirs() creates folder, gives time of modification (with os.path.getmtime). e.g. 1403197510.0
  • write file folder, gives time of modification (with os.path.getmtime). e.g. 1403197510.1
  • windows updates folder, gives modification time (with os.path.getmtime). e.g. 1403197510.19
