For qemu_arm64_defconfig fs/fs.o shows a growth of 260 bytes in .text 
and .data sections.

Change times let users immediately spot which files were modified most 
recently (kernel images, device trees).

If a device stops booting, seeing a file’s change date helps determine 
whether a recent change could be the cause.
