Can you please try to reduce your level of sarcasm on the list?
It's especially irritating when you're simultaneously sarcastic and
factually incorrect:
$ stat /boot/vmlinuz-4.2.6-301.fc23.x86_64

^^^^^^^^^^^^^^^^^^^^^^
Note the ctime
Birth: -
For something more reliable, grub2-mkconfig for similar could do something like:
$ rpm -qf /boot/vmlinuz-4.2.6-301.fc2-queryformat '%{installtime}\n'
with some appropriate provision for packages that don't come from RPM
in the first place.
For human readability:
$ rpm -qf /boot/vmlinuz-4.2.6-301.fc23.x86_64 --queryformat
'%{installtime:date}\n'
Sun 29 Nov 2015 01:01:52 PM PST
Note that this is suspiciously similar to ctime above.
