The passage of time does not seem to affect Mark Harmon's good looks. That makes him the perfect actor to star in "For All Time" (8 p.m., CBS, TV-PG), a time-travel fantasy romance based on an old episode of "The Twilight Zone." Charles Lattimer (Harmon) is a gifted artist, frustrated by his soulless advertising job, his loveless marriage and a world that moves too fast. His home and office are filled with antiques and reminders of a bygone era of civility. So it's perfectly natural that he buys an old stopwatch from a mysterious dealer (Bill Cobbs). A few days later, while commuting, Lattimer spots the dealer in an old-time conductor's outfit just as he is announcing a train stop at a quaint 19th century village. A village only Lattimer can see.
Anyone who has ever seen "The Twilight Zone," or read "Time and Again," or any number of time travel stories can see where this is going. Lattimer meets a charming widow, Laura Brown (Mary McDonnell), the proprietress of the small-town newspaper, as well as her precocious daughter, Kristen (Catherine Hicks, "7th Heaven"). But just because "For All Time" is familiar or predictable doesn't mean it's not watchable in a fun, hokey way .
