One way that I can think of, which is somewhat complicated and not
perfect, is to use grub's date hooks to measure the time between grub
when grub starts to read the grub.cfg, and after it has loaded and
prepared to jump to the kernel. To do that you would add "insmod
datehook; time_start=$HOUR:$MINUTE:$SECOND" to the start of the
grub.cfg, and "time_end=$HOUR:$MINUTE:$SECOND ; save_env time_start;
save_env time_end" on the line after the kernel is loaded. Then after
boot check /boot/grub/grubenv for the values of time_start and
time_end.
