std::time_get<CharT,InputIt>::get_date, std::time_get<CharT,InputIt>::do_get_date - cppreference.com

1) Public member function, calls the protected virtual member function do_get_date of the most derived class.

2)

Reads successive characters from the sequence

[beg, end)

and parses out the calendar date value using the default format expected by this locale, which is determined as

date_order() Format no_order "%m/%d/%y" dmy "%d/%m/%y" mdy "%m/%d/%y" ymd "%y/%m/%d" ydm "%y/%d/%m"

The parsed date is stored in the corresponding fields of the

std::tm

structure pointed to by the argument

t

[edit] Parameters beg - iterator designating the start of the sequence to parse end - one past the end iterator for the sequence to parse str - a stream object that this function uses to obtain locale facets when needed, e.g. std::ctype to skip whitespace or std::collate to compare strings err - stream error flags object that is modified by this function to indicate errors t - pointer to the std::tm object that will hold the result of this function call [edit] Return value

Iterator pointing one past the last character in [beg, end) that was recognized as a part of a valid date.

[edit] Notes

For the alphabetic components of the default date format (if any), this function is usually case-insensitive.

If a parsing error is encountered, most implementations of this function leave *t unmodified.

The implementation may support other date formats besides the ones required by the standard.

[edit] Example

Output:

Parsing the date out of '02/01/2013' in the locale en_US.utf8
Day: 1 Month: 2 Year: 2013
Parsing the date out of '02-01-2013' in the locale en_US.utf8
Parse failed. Unparsed string: -01-2013
Parsing the date out of '2013å¹´02æ01æ¥' in the locale ja_JP.utf8
Day: 1 Month: 2 Year: 2013

[edit] Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR Applied to Behavior as published Correct behavior LWG 248 C++98 eofbit was not set upon reaching the end iterator sets eofbit if a valid date has not been read LWG 461 C++98 do_get_date needed to parse localized date representation parses with the format determined by date_order() [edit] See also parses a date/time value of specified format
