Well actually, there's a boot-time cmdline parameter:
printk.time= Show timing data prefixed to each printk message line
Format: <bool> (1/Y/y=enable, 0/N/n=disable)
And since the code that handles it treats it as a module parameter (even though
it's always builtin), you get this for free:
% ls -l /sys/module/printk/parameters
total 0

-rw-r--r--. 1 root root 4096 Jun 25 11:05 console_suspend
-rw-r--r--. 1 root root 4096 Jun 25 11:05 ignore_loglevel
-rw-r--r--. 1 root root 4096 Jun 25 11:05 time
So save yourselves the embarassment of submitting a patch to add it. ;)
