Describe the bug
cupsd is in infinite loop, causing doing a certain operation (expiring subscriptions/deleting temp printers/removing job files) every second until the service is restarted. The trigger of the issue is unknown, but it happens when a timeout variable (f.e. expire_time or local_timeout) is lower than current_time, causing cupsd to run an operation every second.

To Reproduce
Steps to reproduce the behavior:
Unknown

Expected behavior
No infinite loop after a certain event

System Information:

• seen in Fedora 36/37, NixOS
• cupsd
• CUPS version 2.4.2

Additional context
The additional data here #578 , however the complete error_log is difficult to provide, since we don't know what triggers the issue and once the issue finally shows itself, a ton of logs are provided and it is difficult to track what triggered it. I'll keep my eyes on this.
