Expected results:

The time stamps of the files should be in the past - not in the future, and no warnings should be emitted.

I can't reproduce. Can you please check if I done something wrong while reproducing? 

wget ftp://ftp.mozilla.org/pub/firefox/nightly/latest-mozilla-aurora/firefox-8.0a2.en-US.linux-i686.tar.bz2 
tar xvf firefox-8.0a2.en-US.linux-i686.tar.bz2

This is probably caused by a build machine having an incorrect time set. 16951 is only ~5 hours, so they won't be in the future for very long....we should still try to figure out which machine or machines have this issue, though.

Okay, I was able to reproduce by unpacking mozilla-central build.

BuildID         Revision      Slave                      Current Time status
20110817061121  dcb25d71220d  mv-moz2-linux-ix-slave04   ~ 2hr 10 min slow
20110817030756  630e28e90986  linux-ix-slave33           ~ 7 hours fast

Both have /etc/ntp.conf pointing to ntp.build.mozilla.org, which is ns1.infra.scl1.m.c and ns2.infra.scl1.m.c

Since there are problems within SCL1 (eg linux-ix-slave33), this looks like a problem with the time servers. Over to RelOps.

Actually, I think this is because we're disabling ntpd and and don't force ntpdate on boot for the CentOS builders.

Dupe of bug 649641 which is a dupe of bug 612433, then?

Comment 7

[Phil Ringnalda (:philor)]

And though I thought we usually discussed it in all the clock bugs, neither one of those seems to mention that clock skew not only annoys people untarring Linux builds, it also breaks the clobberer by having the slave be unable to reason correctly about how a thing in its-time compares to a thing in clobberer-time.
