[Cdash] CTEST_NIGHTLY_START_TIME and daylight savings

[Tyler Roscoe]

Information about our time zone, PDT or PST depending on time of year,
is baked into CDash and friends in various places. The CTest script that
drives the builds:

[tylermr at tpb006:~/ng/common/trunk/build/bin/kitt]$ grep PDT *
kitt.cmake:set (CTEST_NIGHTLY_START_TIME "${TP_NIGHTLY_START_TIME} PDT")

In the CMake workflow:

[tylermr at tpb006:~/ng/common/trunk/build/util]$ grep PDT *
SetupTestOptions.cmake:set (CTEST_NIGHTLY_START_TIME "00:01:00 PDT")

As well as in the config for the dashboards themselves: See your CDash
dashboard -> Administration -> Project -> Testing tab.

Maybe I'm just dense but what am I supposed to do here so that Nightly
builds are configured to start at the right time all year long without
manually flipping these bits back and forth every six months?
