Btrfs devel - Mar 2010 - Creation time

From what I could find, btrfs supports only the trinity of UNIX time stamps: 
atime, ctime and mtime.

Is there any plan to support crtime (creation time)?

Side note: ZFS already supports it, ext4 and cifs (samba) are waiting for APIs 
and userland support, so it could be a good time to coordinate efforts and 
solidify the interface.

There is room in btrfs for a fourth time called "otime", but it is not
currently used or even initialized. Once there are APIs, it should be
possible to add crtime support with a slight format upgrade.
