Title: solaris: uptime: Cannot render negative timespan Class: fix Compatible: compat Component: checks Date: 1702991355 Edition: cre Level: 1 Version: 2.2.0p18 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."
