zfs discuss - Dec 2007 - What are the dates ls shows on a snapshot?

Just out of curiosity, what are the dates ls -l shows on a snapshot?  
Looks like they might be the pool creation date.

bash-3.2$ ls -l /home/.zfs/snapshot/
total 15
drwxr-xr-x   9 root     sys            9 Sep 29  2006 
20071126-2328-first-post-move
drwxr-xr-x   9 root     sys            9 Sep 29  2006 20071127-2255-tp-moved
drwxr-xr-x   9 root     sys            9 Sep 29  2006 20071130-2230
drwxr-xr-x   9 root     sys            9 Sep 29  2006 20071206-2148
drwxr-xr-x   9 root     sys            9 Sep 29  2006 20071214-2147

(Those snapshots were created on the dates in their names, somewhere 
near the times.)

The ctime and mtime are from the file system creation date.  The  
atime is the current time.  See:
