Checkmk Werk 15542: Crash MSSQL backup rendering negative timespans

ID: 15542 Title: Crash MSSQL backup rendering negative timespans Component: Checks & agents Level: 1 Class: Bug fix Version: 2.3.0b1 When the hosts' time is running ahead of the servers time the time since last backup can be negative. In this case the MSSQL backup check plugin would crash showing the error message: <b>ValueError (Cannot render negative timespan)</b> Now the check plugin creates a warning result rather than crashing.
