At the end of (every) *.out file simfactory currently outputs:
Mon Jan 20 09:34:59 CST 2020 Simfactory Done at date: 0
where the first is the date as produced by the
date command and the
0 in the second line is
date's exit code. This is due to this Python code
display("Simfactory Done at date: %s" % simenv.system("date")) # This is wrong because system doesn't return the command output
(comment present in source code).
Pull request https://bitbucket.org/simfactory/simfactory2/pull-requests/44/fix-incorrect-use-of-system-date fixes this.
