Yes, atime is last accessed time.

ctime is most likely right. The creation time is not kept under Unix, 
and I don't know it the HFS+ created time can be accessed by 
modifications to standard Unix commands. ctime will be the time of 
the latest chmod, chown, ..., which will be the creation time if none 
of the metedata has been changed since.
