It might be expensive to read the value before every forward to console. I guess it's fine to just read it once at journald startup. It's not really that different from a kernel command line parameter, which cannot changed at runtime. If printk.time is used, the parameter will reflect that.

[systemd-devel] Adding an option to prefix date time when journal forwards messages to console
Hi, We think being able to see the journal message timestamps on console is important. A locked up embedded system where we only have the output of console would be even more useful if we were to know when things went wrong. For this reason, we would like to ask: is it ok if we have such feature in journald.conf? Thanks, Umut ___ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
