JavaTest Message: Test threw exception: java.lang.AssertionError
JavaTest Message: shutting down test

----------System.out:(3/110)----------
Extracted to 2021-11-07T08:38:40Z, expected to be close to 2021-11-07T09:38:41.436Z

Passed = 23 failed = 1
result: Failed. Execution failed: `main' threw exception: java.lang.AssertionError: Some tests failed

The test's start timestamp
end=Sun Nov 07 07\:38\:42 PST 2021

the timestamp retrieved from the last modified attribute of the file == 2021-11-07T08:38:40Z

the timestamp used to set the modified time on the file ==
2021-11-07T09:38:41.436Z

each is an hour out -- this was 7th Nov when DST was ended, but you'd expect the system to have been updated at this time.

a slightly curious failure that might be significant or hinting at some deeper issue.
