Description
The DateTimeS field could not be used to create a date field. The Convert Time Field tool, which is used to do the conversion, failed because of the input date values.
Solution
Inspect the values inside the DateTimeS field and ensure they represent a valid time format. Convert the date values using the Convert Time Field tool, or use Python parsing with Add Field and Calculate Field tools to make a date field.
Alternatively, if a date field is not required, do nothing and use the DateStringS field as a string type.
