In the event that the SAP Hana host is in a timezone other than UTC, the "fileinfo" check could crash reading the error message "ValueError (Cannot render negative timespan)". This has been fixed. If you require this fix, please deploy the agent plugin "mk_sap_hana" to the affected hosts.
The problem was that the modified timestamp of the files was incorrectly converted from local time to UTC. In addition, the reference timestamp (current time) used to calculate file age was determined before the modified timestamp of the SAP Hana files was collected. This could lead to a scenario in which the reference timestamp was older than the modified time of the files.
