Issue New mail stuck in queue with age 23 hours

[ssof]

Server operating system version

CentOS 7.9

Plesk version and microupdate number

18.0.60

I noticed that all emails stay in the queue for about 10 minutes and as soon as a new mail arrives in the queue the age is 23:00 hours.
I removed the outgoing mail control restrictions and there is no greylisting functionality enabled. I switched back and forth from postfix to qmail
but it didn't fix the problem. By the way qmail worked fine. I also checked the log files but there was nothing obvious to me. Any suggestions?

You are saying that the age of the listed emails in the mail queue is incorrect (falsely displaying an age of 23 hours) as soon as a new mail gets added to the queue?

I have exactly the same issue; but on AlmaLinux 8.7.
Mails in added to the queue have a Age of 23:00:00 h at the start. And are not send. Switching timezone will send them away. But switching back to correct timezone the issue is there again.
Datetime settings in Plesk are correct according the 'System Time' page.

Anyone have the same and maybe a solution?

Plesk version: Plesk Obsidian Web Admin Edition 18.0.60 Update

@jvkranenburg are there any errors logged for these message in the mail log? (Tools & Settings > Log Browser >)?
