001165 : Features with invalid date/time values (only includes first 30): <value> = <value>.

Description

NULL values or invalid date/time values were encountered while reading the input feature class.

Solution

Correct or reformat the values in the date/time field specified. If the problem is due to an invalid date/time format, you can use the Add Field tool to create a new Date field, then use the Calculate Field tool to populate it. Often (but not always), Calculate Field will cast nondate fields into a valid date format. Alternatively, select all features with valid (non-NULL) values, then use the Copy Features tool to create a new feature class that only contains valid values.
