Since we don't have evidence for the date of composition of this quartet one way or another, just that it was between 1862 and 1904, leaving it blank - 1862 and 1904 is not ca.1900. (This sort of reasoning, entering the date of publication into the composition date field, leads to entering "ca.1885" because a work was published around 1885 - in a case in which the composer died in 1878, so that this would mean that particular work was said to be composed posthumously.)
