Bug Description
Systemd version(249) in Jammy Jellyfish is too old, When using the Dublin time zone for daylight saving time switching，the CPU usage will suddenly increase to 100% starting from 2024-03-31 00:00:00 and last for 1 hour, but return to normal at 2024-03-31 02:00:00. plz backport the bugfix to v249 or update 255 version in Jammy Jellyfish to fix it. thank you.
