* Add option to display times in ISO 8601 UTC ISO 8601 time is useful when, say, running falco in a container, which may have a different /etc/localtime than the host system. A new config option time_format_iso_8601 controls whether log message and event times are displayed in ISO 8601 in UTC or in local time. The default is false (display times in local time). This option is passed to logger init as well as outputs. For outputs it eventually changes the time format field from %evt.time/%jevt.time to %evt.time.iso8601/%jevt.time.iso8601. Adding this field changes the falco engine version so increment it. This depends on https://github.com/draios/sysdig/pull/1317. * Unit test for ISO 8601 output A unit test for ISO 8601 output ensures that both the log and event time is in ISO 8601 format. * Use ISO 8601 output by default in containers Now that we have an option that controls iso 8601 output, use it by default in containers. We do this by changing the value of time_format_iso_8601 in falco.yaml in the container. * Handle errors in strftime/asctime/gmtime A placeholder "N/A" is used in log messages instead.
