FYI: kernel vs. world time frames for pkgbase: world somewhat after kernel and some related notes

I just did a pkgbase update on aarch64 and looked at the
kernel vs. world timing relationship. The context is:

Tue, 20 Feb 2024
git: b241767f8ef3 - main - Eliminate unnecessary UFS1 integrity checks. Kirk McKusick
git: 3aefe6759669 - main - nextboot: fix typo that merged two args into one Gleb Smirnoff
git: 0c3ade2cf13d - main - nextboot: fix nextboot -k on ZFS Gleb Smirnoff
git: 81dc3a4d3bb9 - main - tools/net80211/wlanwatch: Remove obsolete code. Joseph Koshy
git: 445d3d227e68 - main - msdosfs: fix potential inode collision on FAT12 and FAT16 Stefan Eßer
git: 9dd5023e955d - main - iwm.4: add iwlwifi cross-reference Ed Maste
git: 6a3e87e1306d - main - arp: fix arp -s/-S Gleb Smirnoff
git: 1968d71647ba - main - tests/arp: test arp -s/-S work Gleb Smirnoff
git: e7308a60a5b7 - main - md5: Add test case for GNU input modes. Dag-Erling Smørgrav
git: 4db7ca244705 - main - md5: Fix Perl mode long options. Dag-Erling Smørgrav
git: c05533d97ac1 - main - md5: Fix GNU check mode. Dag-Erling Smørgrav
git: 702f133fa181 - main - md5: Untabify declarations. Dag-Erling Smørgrav
git: fa6a02f50e65 - main - tests/fdgrowtable: open more files in the threaded case Gleb Smirnoff
git: 3ac001620e28 - main - tests/fdgrowtable: remove always true check Gleb Smirnoff
git: e53b83a849e3 - main - tests/sigsys: initialize parameter passed to sysctlbyname() Gleb Smirnoff

The install reports itself as:

# uname -apKU
FreeBSD aarch64-main-pkgs 15.0-CURRENT FreeBSD 15.0-CURRENT main-n268410-445d3d227e68 GENERIC-NODEBUG arm64 aarch64 1500014 1500014

That is:

git: 445d3d227e68 - main - msdosfs: fix potential inode collision on FAT12 and FAT16 Stefan Eßer
CommitDate: 2024-02-20 12:02:24 +0000

However, Looking at /usr/src/tests/sys/kern/sigsys.c shows the
content from:
git: e53b83a849e3 - main - tests/sigsys: initialize parameter passed to sysctlbyname() Gleb Smirnoff
(CommitDate: 2024-02-20 22:37:45 +0000)

So, source somewhat over 10 hrs later than the commit date/time for
what the kernel reported. (But it is just an example. I've little
clue what shortest to longest might be across examples.)

(Note: The next commit's source was not present.)

Looking to futures based on such status for this early pkgbase
context . . .

Identifying the detailed combination of sources one is dealing with
(commits) is a mess as things are so far. Reporting defects based
on testing pkgbase materials is, then, also messy to identify the
context for --or to reproduce the context for.

Similarly, figuring out if a pkgbase update has a source update
that one wants to test can also be messy. Even just being able to
identify the kernel's main-n268410-445d3d227e68 like text for the
published materials (without download or installation of the
actual packages) would be helpful for such. Also having such for
the world build involved would be good.

Food for thought.
