8:34:12 PM User: Hey Josh... Quick question. Got a sec?
8:34:24 PM Josh Moore: Sure. Shoot.
8:35:08 PM User: OriginalFile atime, mtime, ctime aren't documented as to what they are. mtime probably is "modified"... how about (a) and (c)?
8:35:36 PM Josh Moore: access/creation/modification.
8:36:13 PM Josh Moore: These are left in the user space, i.e. the server doesn't try to control them, for example when you access a file the atime is not incremented.
8:36:32 PM Josh Moore: It's basically to allow clients to write as much info as is available on the linux file system into the db.
8:36:40 PM User: All in "file system" terms as opposed to "biologist" frame of ref, where creation could be "acquisition" timestamp...
8:37:52 PM Josh Moore: Exactly. Acquisition information is else where in the data model.
8:38:49 PM User: ... if put in there. Thanks! That's what I needed to know.
8:39:03 PM Josh Moore: No problem.
