I don't see any difference in the > output of ls -lT whether the sysctl is set to 0 or 1. It is visible for userspace, but I guess not for ls(1). You can test it by doing: echo foo > foo echo bar > bar diff -u foo bar And it prints the header at the top with the raw timestamps. It's not really useful for a regular user to see the nanoseconds, but for tools like make(1) and others that depend on timestamps to do decision making, it would be nice to have. --=20 Ed Schouten <ed@80386.nl> WWW: http://80386.nl/ --jk5HhkA9Kov5Oxsi Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (FreeBSD) iQIcBAEBAgAGBQJPNUsJAAoJEG5e2P40kaK7j9YQAId2XvJhCprq8eIbxa1pVuqo JnJOEiwdyci6ZAKhwvCCyAM4ZkARhnirp/v9kWy7rQWwMfojgxglC64L2SbpLaBO EDPgRQ1ORrvi8lcR83vtbXldOSDTCBG+i/R8RoEfEw6WXCx5RITdPRhLspG8TqfU fYOcXkPjq96iNyoXfmaKXSim4MgGHzrFp1Ulc43reS2Ly7hGYO8AHNWKKbLgtedl DKvbD0i3fN1Rn+LLDvBhmM8N9iScarKJgsCgSGKmwJevduxgr1uojhmXfPBwiTO/ 5RKnyOSUdRxmMOnssgaVkSKwu4I7m5FvA1NF4dq5c5TZdSSB8aESCcoLiFAp4LaR 2SlCLp5+p50DGv/pqNcQBuDdBPSH9SklXczZdwtbRLkwJhumFZvUONJ4zWotO/rl F1l2XD8pIM6vIJ/tBCpymemnnBl9h0KZcWHyKTgd2G09B/qi+f7yOG3kHNwAshrm TJNbrsPG7CvmQlyeWZY1vykaq6SpX/ZcSliEoODe60ix0hPU30/pMISVSIkwqVNe CXOmHuOMgJSzvDT6621bDQsCMv1Qid3p2IyuBuJDPM7Qs76j0/OqnDkYjJncIyvp Ep9XJZlCeRA79EKBfutIXZq21Jp+H4rXbz+N6/JJRHbWUyzyCL+fMyxBoHDLaIUj QN3W1X8ZkcQ1R+Cf3kSG =iM8N -----END PGP SIGNATURE----- --jk5HhkA9Kov5Oxsi--
