[//]: # (werk v2) # solaris: uptime: Cannot render negative timespan key | value ---------- | --- date | 2023-12-19T13:09:15+00:00 version | 2.3.0b1 class | fix edition | cre component | checks level | 1 compatible | yes Solaris server may keep a bad time when moved to different hardware. This is corrected some minutes after booting via NTP server. If the checkmk client is used before the time has been corrected, it was possible that a negative time span was reported for the time since the last start. This caused a crash in the check. The new behaviour is, that the check will report an UNKNOWN status alongside the message: "Your Solaris system reported to be booted in the future."
