<p><tt>According to this, Turkey did not only not turn the hour back
from +3h to +2h as otherwise in October at the end of DST,<br>
but in 1978 moved from +3h to +4h on 14 Oct 1978.</tt></p>
<p><tt>It did move standard time forward AND did not end DST.</tt></p>
<p><tt>Is there any source for this fact? The comment does not show
any.</tt></p>
<p><tt>Or is it a bug? Arthur Olson writes that the clocks were not
back. But were they actually turned forward?<br>
