class Realize::Format::Date
Formats a date/time value. If the input is nil, it will output nil. If an input_format
is configured then it will use that to explicitly parse it. If an input_format
is not specified then it will use Ruby's DateTime#parse heuristics for parsing. By default, the output format is ISO-8601 standard (YYYY-MM-DD). It is also possible to have this output formatted time as well, but since it is named 'format_date', it is assumed you want something date-only.
See this link for more information about Ruby's DateTime parsing and formatting details and also for valid format tokens: ruby-doc.org/stdlib-2.6.6/libdoc/date/rdoc/DateTime.html#method-i-strftime
