which you provided shows that you do indeed have data which is at least as recent as 2014f, which is what you need for the upcoming Russian changes.<br><br>As Arthur David Olson mentioned in <a href="http://mm.icann.org/pipermail/tz/2014-August/021547.html" target="_blank">http://mm.icann.org/pipermail/tz/2014-August/021547.html</a>, the most likely scenario comes from the fact that the hour from 01:00:00 to 01:59:59 is repeated in zones like Europe/Moscow on 2014-10-26. So, when you run:<br>
<span style="font-family:courier new,monospace">date -s "Sun Oct 26 01:59:00 MSK 2014"</span><br></div>...your system is assuming that you mean the <b>second</b> occurrence of 01:59:00, which is 59 minutes <b>after</b> the changeover from 01:59:59 back to 01:00:00 has already happened.<br>
<br></div>You can get around this by setting the date according to UTC, one minute before the expected changeover:<br></div><span style="font-family:courier new,monospace">date -s "Sat Oct 25 21:59:00 UTC 2014" -u</span><br>
<br></div>Alternatively, if you're very patient, you could set the time to 00:59:00, which only happens once that day:<br></div><span style="font-family:courier new,monospace">date -s "Sun Oct 26 00:59:00 MSK 2014"</span><br>
</div>...and then wait 61 minutes to make sure the changeover happens as expected.<br>
