@IsTimestamp annotation

Action

Requires that the value be a timestamp value. If it is not, it will attempt to perform a conversion according either using a provided pattern, or using the locale-dependant default pattern. Usually date conversions are performed automatically. You should use this annotation only if you want to specify a custom date pattern.

Javadoc Ref : @IsTimestamp

Input Types ¹	Object
Output Types	java.util.Date or String

¹Automatic conversion will take place if the provided input does not match any of the input classes, as described in the conversions part of the manual.

Arguments
