[DATE] Change Creation and/or Modification Date of Selected Finder Item

Clearly, the API Keyboard Maestro ([NSFileManager attributesOfItemAtPath:error:]) uses does not deal with returning sub-second times.

It is possible the API does allow setting then dates with sub-second times, which is why you see that working.

Sorry, you’ll need to find an alternative way to get the modification date with sub-second accuracy.
