Description Benni Hill 2013-04-24 21:14:48 UTC 
In kio_nfs.cpp:801 st_ctime is treated as the creation time but according to stat.h st_ctime is the status change time.
At line 819 something similar seems to happen.

From stat.h:
    __time_t st_atime;			/* Time of last access.  */
    __syscall_ulong_t st_atimensec;	/* Nscecs of last access.  */
    __time_t st_mtime;			/* Time of last modification.  */
    __syscall_ulong_t st_mtimensec;	/* Nsecs of last modification.  */
    __time_t st_ctime;			/* Time of last status change.  */          <<<------
    __syscall_ulong_t st_ctimensec;	/* Nsecs of last status change.  */

Reproducible: Always

nfs: Do not set UDS_CREATION_TIME

attributes.ctime is not the file birth time but the inode
(file metadata) change time, which is not supported in KIO.
