I have a feature request that is somewhat related to Allow configure log in system timezone.
I would like to be disable the timestamp in log messages all together. In my use-case, the system (coreos, systemd, journalctl) takes care of logging and already prepends each line with timestamp and process information (hostname, process name, pid). This means that currently, the time is visible twice on each line. Being able to disable the timestamp in the logs would be nice.
