The patch is fine, please commit it. I ran the tests on my teensy laptop
(with a RAMdisk) and got:

    real 31m22.361s
    user 21m42.720s
    sys 15m50.920s

Summing up the ELAPSED lines from tests.log yields:

    00:31:21.28

So it would appear that we're calculating test duration correctly. If
the discrepancy between reality and what JUnit reports is bigger htan
this second or so, the problem is clearly in the log file parser, not in
the elapsed time calculation.
