What happens is when a PS3 has never been connected to PSN... the user accounts you create contains a "dummy" ACCOUNT_ID PARAM.SFO - PS3 Developer wiki
Instead of a valid ACCOUNT_ID all these user profiles contains an ACCOUNT_ID filled with zeroes (and this dummy ACCOUNT_ID is used by the firmware to create the savegames, trophies, etc...)
What i dont know is what happens when you register in PSN one of these accounts with a "dummy" ACCOUNT_ID
Though i always speculated the process takes some minutes because is needed to "rebuild" all the savegames and trophies of the user (to add the new ACCOUNT_ID in them replacing the zeroes)
Now it seems you are confirming my theory... the PS3 is able to rebuild them (this was obvious because rebuilding them is one of the native functions)... but you are also confirming sony servers considers them valid after the rebuild (this was not so obvious because they could simply refuse to validate trophies unlocked from a non-registered machine/account to avoid risks of cheating/tampering with them)
So i guess if you want to revert back the PS3 firmware to the state where doesnt stores timestamps... the first step is to delete your account
And then associate the old trophies with a new non-registered account... and then register the account again in PSN

If there is some error in what i just said please correct me, half of it is speculative and deduced years ago but never tested by myself
