Utility functions concerning the OCaml-runtime
last_accessed path
returns the time path
was last accessed.
For files, the access time is updated whenever the file is read or executed.
Note that some filesystems do not implement access time updates, or may allow
mounting with access time updates disabled.
last_modify path
returns the time the file at path
was last modified.
For files, the modify time is updated whenever path
is written to, or if
its status attributes are updated.
last_changed path
returns the time path
last had its status changed.
This is not the same as last modified, as the last status change will also
be updated if path
's ownership or permissions change.
