Class IllFormedDateCorrector

java.lang.Object
org.eclipse.epsilon.rdf.emf.IllFormedDateCorrector
public class IllFormedDateCorrector extends Object

Corrects ill-formed xsd:dateTime, xsd:dateTimeStamp and xsd:date literals into valid ones, by adding or removing components as needed. For instance, "2026-09-10"^^xsd:dateTime is corrected to "2026-09-10T00:00:00"^^xsd:dateTime.

Missing time components default to zero, missing timezones are only added for xsd:dateTimeStamp (as UTC), and month/day/hour/minute/second values are zero-padded. Literals which cannot be corrected are left as is.
