template<typename _CharT, typename _InIter>
class std::time_get< _CharT, _InIter >
Primary class template time_get.
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 time_base::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 time_base::dateorder::noorder.
NOTE: The library always returns noorder at the moment.
Returns
A member of time_base::dateorder.

do_get() and get().
Parameters
| __s | Start of string to parse. |
|---|---|
| __end | End of string to parse. |
| __io | Source of the locale. |
| __err | Error flags to set. |
| __tm | Pointer to struct tm to fill in. |

◆ get() [2/2]
template<typename _CharT , typename _InIter >
◆ get_date()
template<typename _CharT , typename _InIter >
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.
Parameters
| __beg | Start of string to parse. |
|---|---|
| __end | End of string to parse. |
| __io | Source of the locale. |
| __err | Error flags to set. |
| __tm | Pointer to struct tm to fill in. |
Returns
Iterator to first char beyond date string.

References std::time_get< _CharT, _InIter >::do_get_date().
◆ get_monthname()
template<typename _CharT , typename _InIter >
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.
Parameters
| __beg | Start of string to parse. |
|---|---|
| __end | End of string to parse. |
| __io | Source of the locale. |
| __err | Error flags to set. |
| __tm | Pointer to struct tm to fill in. |
Returns
Iterator to first char beyond month name.

References std::time_get< _CharT, _InIter >::do_get_monthname().
◆ get_time()
template<typename _CharT , typename _InIter >
Parse input time string.
This function parses a time 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_time().
If there is a valid time string according to format X, tm will be filled in accordingly and the returned iterator will point to the first character beyond the time string. If an error occurs before the end, err |= ios_base::failbit. If parsing reads all the characters, err |= ios_base::eofbit.
Parameters
| __beg | Start of string to parse. |
|---|---|
| __end | End of string to parse. |
| __io | Source of the locale. |
| __err | Error flags to set. |
| __tm | Pointer to struct tm to fill in. |
Returns
Iterator to first char beyond time string.

References std::time_get< _CharT, _InIter >::do_get_time().
◆ get_weekday()
template<typename _CharT , typename _InIter >
Parse input weekday string.
This function parses a weekday name and puts the results into a user-supplied struct tm. The result is returned by calling time_get::do_get_weekday().
Parsing starts by parsing an abbreviated weekday name. If a valid abbreviation is followed by a character that would lead to the full weekday 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.
Parameters
| __beg | Start of string to parse. |
|---|---|
| __end | End of string to parse. |
| __io | Source of the locale. |
| __err | Error flags to set. |
| __tm | Pointer to struct tm to fill in. |
Returns
Iterator to first char beyond weekday name.
Definition at line 513 of file locale_facets_nonio.h.
References std::time_get< _CharT, _InIter >::do_get_weekday().
◆ get_year()
template<typename _CharT , typename _InIter >
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.
Parameters
| __beg | Start of string to parse. |
|---|---|
| __end | End of string to parse. |
| __io | Source of the locale. |
| __err | Error flags to set. |
| __tm | Pointer to struct tm to fill in. |
Returns
Iterator to first char beyond year.
