This facet encapsulates the code to parse and return a date or time from a string. It is used by the istream numeric extraction operators.
The time_get template uses protected virtual functions to provide the actual results. The public accessors forward the call to the virtual functions. These virtual functions are hooks for developers to implement the behavior they require from the time_get facet.

Return preferred order of month, day, and year.
This function returns an enum from timebase::dateorder giving the preferred ordering if the format "x" given to time_put::put() only uses month, day, and year. If the format "x" for the associated locale uses other fields, this function returns timebase::dateorder::noorder.
NOTE: The library always returns noorder at the moment.

Parse input date string.
This function parses a date according to the format "X" and puts the results into a user-supplied struct tm. The result is returned by calling time_get::do_get_date().
If there is a valid date string according to format "X", tm will be filled in accordingly and the returned iterator will point to the first character beyond the date string. If an error occurs before the end, err |= ios_base::failbit. If parsing reads all the characters, err |= ios_base::eofbit.

Parse input month string.
This function parses a month name and puts the results into a user-supplied struct tm. The result is returned by calling time_get::do_get_monthname().
Parsing starts by parsing an abbreviated month name. If a valid abbreviation is followed by a character that would lead to the full month name, parsing continues until the full name is found or an error occurs. Otherwise parsing finishes at the end of the abbreviated name.
If an error occurs before the end, err |= ios_base::failbit. If parsing reads all the characters, err |= ios_base::eofbit.

Parse input year string.
This function reads up to 4 characters to parse a year string and puts the results into a user-supplied struct tm. The result is returned by calling time_get::do_get_year().
4 consecutive digits are interpreted as a full year. If there are exactly 2 consecutive digits, the library interprets this as the number of years since 1900.
If an error occurs before the end, err |= ios_base::failbit. If parsing reads all the characters, err |= ios_base::eofbit.
