Slowness execution time output in seconds instead of milliseconds

Slow tests often run for over 1 second. The output of 1000 milliseconds or more
can be harder to read the longer the test runs. Using seconds inserts a decimal
to make output easier to read for humans.

For example, a slow test running for 12432 milliseconds displays as 12.432 seconds
