This is what I get for the last one:

--8<---------------cut here---------------start------------->8---
sqlite> select * from validpaths where path = 
'/gnu/store/q6qa5s2z2l20q25qpxyfv1wni5wwhk24-flightgear-2018.3.5';
48732920|/gnu/store/q6qa5s2z2l20q25qpxyfv1wni5wwhk24-flightgear-2018.3.5|sha256:86426115e1f49835a24612ae89a180e87ac835332b4e83d19ecbd43211336cd2|1623360391|/gnu/store/722yyaa1qvkaakn6p7ywwr4dnm5wmddz-flightgear-2018.3.5.drv|-1610199336
--8<---------------cut here---------------end--------------->8---

The registration date is:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> ,use(srfi srfi-19)
scheme@(guile-user)> (date->string (time-utc->date (make-time time-utc 0 
1623360391)) "~1" )
$164 = "2021-06-10"
--8<---------------cut here---------------end--------------->8---

I thought so too (commit 13a7d2a538b00aa0a8cf9b999f1a4ff3e5959af9)!
So we must be using another code path.

Mathieu, these store items get registered via an RPC, or via (guix store
database)?

Thanks,
