[Bug libstdc++/26701] New: std::time_get parses only 2 digits of year, in en_GB locale.

["murrayc at murrayc dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The attached test case shows that std::time_get<> parses only the first 2
digits of years, and assumes that those are years in the 1900s. This is a loss
of data. 

It gives this output, in an en_GB locale:
murrayc@ubuntumurrayc:~$ ./a.out
The date as text: 01/02/2003
std::time_get result: day=1, month=2, year=1920

Maybe time_get tries to use the strftime date format only, which uses 2 digits
only for display in en_GB.
