...ic' vectors are really supported, although it does say The default method does not allow factors, but works with objects sufficiently like numeric vectors that ?sort?, addition and multiplication work correctly. In principle only sorts and weighted means are needed, so datatimes could have quantiles - but this is not implemented. There is no claim that it works (let alone works well) for class "difftime".
