Extended Manipulators 31.7.8 [ext.manip] p8 defines the semantics of `get_time` in terms of a function `f`.

Note the call to `tm.get`. This is clearly an error, as `tm` is a type and not an object. I believe this should be `tg.get`, rather than `tm`, but this is not my area of expertise.

Proposed resolution:

Change 31.7.8 [ext.manip] p8:

>     template <class charT, class traits>
>     void f(basic_ios<charT, traits>& str, struct tm* tmb, const charT* fmt) {
>        typedef istreambuf_iterator<charT, traits> Iter;
>        typedef time_get<charT, Iter> TimeGet;

>        ios_base::iostate err = ios_base::goodbit;
>        const TimeGet& tg = use_facet<TimeGet>(str.getloc());

>        tgm.get(Iter(str.rdbuf()), Iter(), str, err, tmb, fmt, fmt + traits::length(fmt));

>        if (err != ios_base::goodbit)
>            str.setstate(err):
>     }
