In a recent paper [1] (also at http://lanl.arxiv.org/abs/0803.3721), I madeseveral critical remarks on a 'Hermitian time operator' proposed by Galapon [2](also at http://lanl.arxiv.org/abs/quant-ph/0111061). Galapon has correctly pointed out that remarks pertaining to 'denseness' ofthe commutator domain are wrong [3]. However, the other remarks still apply,and it is further noted that a given quantum system can be a member of thisdomain only at a set of times of total measure zero.
