I tried this but unfortunately it doesn't seem to work as is expected.
On the host I tried it, following packages are upgraded when I did
`pkg upgrade` last time.
p5-URI-5.06
p5-Module-CoreList-5.20210120
rubygem-bundler-2.2.7_1,1
sudo-1.9.5p2 1611721387
And I got following result.
yasu@eastasia[1213]% pkg query -e %t=$(pkg query %t | sort -n | tail -n1) %n-%v
p5-Module-CoreList-5.20210120
p5-URI-5.06
yasu@eastasia[1213]%
So I checked timestamp of install packages.
yasu@eastasia[1216]% pkg query -a '%n-%v %t' | sort -k 2 -n -r | head -10

p5-URI-5.06 1611721389
p5-Module-CoreList-5.20210120 1611721389
rubygem-bundler-2.2.7_1,1 1611721388
sudo-1.9.5p2 1611721387
p5-Config-General-2.63 1611685127
libunwind-20201110 1611685127
bind916-9.16.11 1611685127
zstd-1.4.8 1611685126
sqlite3-3.34.1,1 1611685126
bind-tools-9.16.11 1611685125
yasu@eastasia[1217]%
As you can see timestamps of rubygem-bundler-2.2.7_1,1 and sudo-1.9.5p2
are smaller than that of p5-URI-5.06 and p5-Module-CoreList-5.20210120.
So they aren't included in the list.

According to the above result, it doesn't seem to be true. And I think
it's quite possible. When packages are upgraded they are upgraded not
in parallel but sequentially. So let me assume following situation.
* Pakcage A and B are to be upgraded.
* A is upgraded first and B is next.
* Both are quite large package.
* Host is low-spec.
In this case upgrade of each package may take a few minutes. And it
result in that there is difference of a few minites between the
timestamps of them after upgrade.

This didn't hit upon me and I think it's really excellent way to use
file for timestamp. I'll use it in my shell script. Thank you for
letting me know.
