Add the human format support to the test tool so that
GIT_TEST_DATE_NOW can be used to specify the current time.

The get_time() helper function was created and and checks the
GIT_TEST_DATE_NOW environment variable. If GIT_TEST_DATE_NOW is set,
then that date is used instead of the date returned by by
gettimeofday().

All calls to gettimeofday() were replaced by calls to get_time().

Renamed occurances of TEST_DATE_NOW to GIT_TEST_DATE_NOW since the
variable is now used in the get binary and not just in the test-tool.
