from anyone so I dove in the CTest source code (cmake-2.8.1) and found the
answer. I recommend that this information below about how ctest_update is
implemented (at least for subversion) should either be logged in the stdout
stream (please show actual svn command) or be included in the documentation
somewhere. This issue had been a problem for us for over a week and we
wasted a lot of time trying to figure it out.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Hi, I have a question about using CTest for automatic
nightly builds. Our company has been using CMake/CTest/CDash tools for
about a year now with no problems when the nightly build time was at 1am.
We moved the nightly build time to 9pm because now we have a lot more software
to build and many more compilers. We changed all the projects nightly
start time (on the CDash server) to 6pm to ensure the nightly builds show up
for the next day. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>However the problem we are seeing is that CTest_Update does not
seem to update to the head revision anymore, but rather seems to update to the
previous day’s revision? I have found a few posts suggesting that
the variable CTEST_NIGHTLY_START_TIME is not used anymore? Is this
true? All of our ctest config files had set this value to midnight
because I think it was required in older versions of CMake/CTest? Is it
possible that this old behavior/capability of using this client-side variable
is still present and is causing our svn update problem? From the output
log of the svn update command it appears that the nightly start time is
affecting the svn update operation to update to yesterday’s
revision. Can I just remove the Set (CTEST_NIGHTLY_START_TIME) command
from our client update ctest scripts to fix this problem? Will older
versions of CMake require this variable to work?<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Below is the log output of the CTest/CDash update script we
use to recursively update our repositories. You can see where the nightly
start time is set, and how the old revision number is newer than the new
revision number.<o:p></o:p></span></font></p>
