OS Specific Fact Names
First Come First Served
Unix
Unix.ctime
"time-val" from
From IEEE Std 1003.1-2004 XBD 4.7 "File Times Update" :
"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
From IEEE Std 1003.1-2004 XBD 4.7 "File Times Update" :
"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.
Unix
Unix.ownername
"1*RCHAR" from
File owner name, as mapped from the numeric owner ID, by the operating system.
Unix
Unix.groupname
"1*RCHAR" from
File group name, as mapped from the numeric group ID, by the operating system.
