as an alternative (or addition?) to feature request / bug 6536:
mclient's default timing mode should (again) be "none" rather than "clock"
much like feature request / bug 6536 this is mainly to avoid that the default timing output compromises/invalidates the format of mclient's output formatters csv, tab, xml.
Changeset 01645d98a71b, made by Stefan Manegold <Stefan.Manegold@cwi.nl> in the MonetDB repo, refers to this bug.
