附加信息

When a null value is passed to the Arcade Date function, it gets implicitly converted to the number 0. Date(0) will return the date based on the number of milliseconds since Jan 1 1970 UTC (in this case 0). To avoid this implicit casting, add null checks in the Arcade expression. Documentation on implicit casting: https://developers.arcgis.com/arcade/guide/type-casting/#implicit-number-casting Date function documentation: https://developers.arcgis.com/arcade/function-reference/date_functions/#dateepoch---date

解决办法

Check for null values before creating the date and passing it into the DateDiff function:

var retire = $feature["dateField"]; //.

This is already a date field, and does not need to use the Date() function if (!IsEmpty(retire)) { return IIF(DateDiff(Now(), retire, 'days') >= 0, "retired", "active") } returns null.
