Proper formatting for DateTime Index

See original GitHub issue

As an extension to #2124, a warning can be included that assesses whether the date has been properly formatted. It might be useful to have certain default formats for dates that are passed in, such as mm/dd/YYYY %H:%M:%S.

For example, in some cases, Pandas will infer the year 55 as 2055 and then 77 as 1977. This would entirely misconstrue the timeline of data. Users should be encouraged to format their datetime column/index to include the full year.

@thehomebrewnerd thank you for that context. Good to know we have that support in woodwork currently.

I will close this and file a separate issue in woodwork to track a “smart inference” feature.

@dsherry @ParthivNaresh Would a Woodwork solution throw a warning/error if the datetime column is not properly formatted? Seems that we need a validation check for the Datetime Logical Type.
