# usage: suite_times [ status.log ]
#
# Parses a "status.log" file for a suite job, and for each test that
# ran, report these timeline data from the log:
#   1. hostname of the DUT that the test ran on
#   2. time_t value of the time that the test started running
#   3. total run time of the test on the DUT
#   4. number of seconds between this test's start time and the
#       start time of the last prior test on the same DUT
#   5. name of the test
#
# This script is meant as a simple building block.  Below are
# some sample uses.
#
# Print average inter-test time:
#   suite_times | awk '{if ($4) {sum += $4; cnt++}} END {print sum / cnt}'
#
# Print average test run time:
#   suite_times | awk '{sum += $3} END {print sum / NR}'
#
# Print time line for a host:
#   suite_times | grep $HOST
