D5138: Fill UDS_CREATION_TIME with the value of st_birthtime on FreeBSD

[Adriaan de Groot]

adridg added a comment.


  Might want to add a comment about "this is the actual inode creation time; support depends on the underlying filesystem (e.g. UFS and ZFS have this information, NFS doesn't)", and change the comment about buff.st_ctime and KDE 2.0.
  
  In addition, please insert the creation time information only if buff.st_birthtime is useful. On an FS that doesn't support the information, you'll get 0; but time_t is (on FreeBSD x86 anyway) signed, so 0 or < 0 are in theory legitimate timestamps; for simplicity probably use only positive timestamps.
  
  On Linux (replying to DFaure), ext4 supports birthtime (crtime), but stat(2) doesn't have a way to report that information; I'll dig into GNU coreutils a little (e.g. 20 minutes, tops) to see how they get at, and report, the information.
