Should we keep the formatting same as kernel then?

[   16.380000] systemd-journald[376]: Received request to flush runtime journal from PID 1

Is there a way to get notified when the value of /sys/module/printk/parameters/time is changed? It might be expensive to read the value before every forward to console.
