[//]: # (werk v2) # Handle years in ntp output key | value ---------- | --- date | 2024-08-27T11:12:57+00:00 version | 2.3.0p14 class | fix edition | cre component | checks level | 1 compatible | yes This werk affects you, in case your last `ntpq` synchronization was indeed more than a year ago. A potential check crash traceback looks like: ``` File "/omd/sites/SITE/lib/python3/cmk/base/plugins/agent_based/ntp.py", line 67, in _ntp_fmt_time return int(raw) ValueError: invalid literal for int() with base 10: '3y' ``` The year case is now handled in the parse function.
