[Cdash] Does cdash detect changes in a test timing

Huh.
If you look at September 20's test result page:
http://www.cdash.org/CDash/testDetails.php?test=115301959&build=1548885
You see "Execution Time (s) 2.65 (mean:2.66 std:0.03)" and "Test Timing: Passed"
Then for subsequent days (9/21 through 9/25 ... and similarly beyond):
"Execution Time (s) 16.25 (mean:6.74 std:5.21)"
"Execution Time (s) 16.27 (mean:9.60 std:5.69)"
"Execution Time (s) 16.20 (mean:11.58 std:5.39)"
"Execution Time (s) 16.26 (mean:12.98 std:4.85)"
"Execution Time (s) 16.24 (mean:13.96 std:4.25)"
....but always with "Test Timing: Passed" even though the timing and
the std. deviation shot through the roof on 9/21.
I've not looked at the CDash code that measures/detects the test
timing, but it does seem like there is probably something wrong with
it.
Sure smells like a CDash bug in here.
