Hello, I have a txt file with a 1st column as a date and a 2nd column as data. I am trying to read this file into a STL sequence. The format of the date varies. Is there a utility function to try different(all) dates formats until it finds a valid date when it attempts to read that 1st column? Or should I just construct a list of possible date_input_facets and try each of them until >> succeeds? Regards,
