When using the elapsed time logging, an extra 0 gets inserted in the log.
Below are two comparisons of a logged bootup from the same Linux embedded device.
The first log was done with local time, the second with the "elapsed time (logging)" option.
As you can see, the SF: 2097152 line took 515ms when using local time logging, but when using elapsed time logging, it reports that it took from 3.0875 to 4.0391s, or 0.9516s. I think it actually took from 3.875 to 4.391s, or 0.516s.
This is a fairly consistent step, bulk loading the Linux kernel from SPI flash, so the speed should be pretty consistent boot to boot.
