trying to use std::get_time to parse YYMMDD and failing

Question

I\'m trying to do this and failing:

std::istringstream ss(\"1212\");
ss >> std::get_time(&t, \"%y%m\");
if (ss.fail()) // every time!

Answer 1

Visual Studio does not seem to implement the spec properly, nor did GCC until version 5.0. If you continue to use std::get_time with VS13 or even VS15, you will need to manually add delimiters to be able to parse times until they finally get around to realizing this bug.
