Unix Unix.ctime "time-val" from [RFC3659]

From IEEE Std 1003.1-2004 XBD 4.7 "File Times Update" [http://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap04.html#tag_04_07]: "st_ctime is associated with the times that the file status is changed."

This is clarified in the operations described throughout IEEE Std 1003.1-2004 XSH 3 "System Interfaces."

Although IEEE Std 1003.1-2004 only considers st_ctime as having second resolution, platform-specific extensions exist that provide st_ctime semantics but with sub-second resolution. Unix.ctime values from such platforms MAY use such finer-grain resolution.

Unix Unix.atime "time-val" from [RFC3659]

From IEEE Std 1003.1-2004 XBD 4.7 "File Times Update" [http://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap04.html#tag_04_07]: "The st_atime field is associated with the times that the file data is accessed."

This is clarified in the operations described throughout IEEE Std 1003.1-2004 XSH 3 "System Interfaces."

Although IEEE Std 1003.1-2004 only considers st_atime as having second resolution, platform-specific extensions exist that provide st_atime semantics but with sub-second resolution. Unix.atime values from such platforms MAY use such finer-grain resolution.

For performance reasons, some platforms allow operations to delay or suppress updates to st_atime. FTP servers on such platforms MAY refrain from publishing the Unix.atime fact.
