While working on reproducible builds for openSUSE, I found that our `cmake-4.1.1` package fails the CTestTestStopTime test when run on or after 2038-01-01. My guess is that the Tests/CTestTestStopTime/GetDate.cmake code somehow gets an overflow in a signed 32-bit int. The test log had: ``` Test project /home/abuild/rpmbuild/BUILD/cmake-full-4.1.1-build/cmake-4.1.1/Tests/CTestTestStopTime Start 1: TestSleep 1/2 Test #1: TestSleep ........................ Passed 30.00 sec Start 2: ShouldNotRun 2/2 Test #2: ShouldNotRun .....................***Failed 30.00 sec 50% tests passed, 1 tests failed out of 2 Total Test time (real) = 60.00 sec The following tests FAILED: 2 - ShouldNotRun (Failed) Start 221: CTestTestSubdir ```
