This error message
Errors while reading device logs: Wall Clock adjustment detected - results might be strange while using --endis not a failure message. @vitek-karas fixed xharness to not report it as error but a warning. I think we should close this issue as it's matching a vast range of failures on a message that is not relevant.kotlarmilos commentedon Jul 15, 2026
Yes, this is wrong and it masks real failures. Closing this issue. If we want to keep it open then a new regex is needed.
