Sorry for the terse information, here's a more detailed explanation:
- btime - Birth Time - When the object was created
- ctime - Change Time - The last time metadata for the object was changed
- mtime - Modification Time - The last time raw data for the object was changed
- atime - Access Time - The last time the object was accessed (read or written)

Hi Quincey
thanks for clarifying this. Unfortunately it seems that for me only ctime
is non-zero... I will take a look into it.
Thanks a lot!

Ah, the other fields aren't updated by the library yet.

Hi Quincey,
how would "access time" work, is it supposed to modify a read-only-openes file?
It sounds like a cool feature, but I'd be wondering how deal with such constraints like even read-only filesystems.

If a file is opened read-only, none of these times will be changed.
