// Effects: If m.ok() == true inserts format(os.getloc(), fmt, m) where fmt is "%b" widened to charT.

// Effects: Streams m into os using the format specified by the NTCTS fmt.
// fmt encoding follows the rules specified in 25.11.

//
// Effects: Attempts to parse the input stream is into the month m using the format flags
// given in the NTCTS fmt as specified in 25.12. If the parse fails to decode a valid month,
// is.setstate(ios_- base::failbit) shall be called and m shall not be modified.
// If %Z is used and successfully parsed, that value will be assigned to *abbrev if
// abbrev is non-null. If %z (or a modified variant) is used and successfully parsed,
// that value will be assigned to *offset if offset is non-null.
