19 //   Effects: Inserts format(fmt, d) where fmt is "%d" widened to charT.

26 //   Effects: Streams d into os using the format specified by the NTCTS fmt.

36 //             given in the NTCTS fmt as specified in 25.12.
37 //             If the parse fails to decode a valid day, is.setstate(ios_base::failbit)
38 //             shall be called and d shall not be modified.
39 //             If %Z is used and successfully parsed, that value will be assigned to *abbrev
40 //             if abbrev is non-null. If %z (or a modified variant) is used and
41 //             successfully parsed, that value will be assigned to *offset if offset is non-null.
