Formatter for date to have consistent Format #1195
Description
Motivation / Current Behaviour
For the data.h class, the output of a selected day currently can be done ..."{}-{}-{}", date.day, date.month, date.year...
However, we want so go with a consistent format (f.e. ISO format). Therefore, it would be better to have a formatter in the date.h class.
