I think there are some other considerations here with date-time. What if you want to replace the short or long strings associated with a month output? Or I want the 'days of the week' be 'day1', 'day2', instead of 'Sun', 'Mon', etc. For these cases I think the strings need to get associated with a facet instead of a fleeting i/o manipulator.
You are right. However there are legitimate cases where I might want both. That is, override the locale-specific month names using a facet _and_ choose a strftime-style date format independently. So I think that you need both a facet (for storing locale-dependent information for %a, %A, %b, %B, %c, %p, %r, %x, %X, and the other locale-dependent specifiers) and a manipulator for the format string.
