But given that it works, is it actually necessary, that xapian
apparently pulls an int from the database, returns a std::string to
libnotmuch, which calls a helper function to unserialize it to a double
and casts it to time_t before handing it to the user how probably uses
it as a long?

Can't we easily put in longs and get longs back?
