On the Protophysics of time. Reply to H. Andreas* critique along with a remark on the scope of operational foundations of measurement. In 2004, H. Andreas presented in this journal a refutation of Janich's operational foundation of time measurement. Pursuing suggestions made by F. Mühlhölzer in 1981, Andreas intends to show that Janich's proof of the uniqueness of the operationalization that he suggested fails. It is shown that Andreas' arguments, like Mühlhölzer's, are mistaken and do not challenge Janich's theory. Some (...) remarks on the scope of Protophysics are added, which may lead to a more substantial discussion of the merits of Janich's approach. (shrink)
