well, if there is a tool that believels that there will always be [ (part
of timestamp marker) as the first symbol then that tool has a problem. there
is no "guaranteed" format of console messages. one can print

	pr_err("message\n message\n message\n);

or one can compile the kernel with no CONFIG_PRINTK_TIME.

or one can disable printk_time via printk_time module param.
