Class MailDateParser

java.lang.Object

org.apache.tika.parser.mailcommons.MailDateParser

public class MailDateParser
extends Object

Dates in emails are a mess. There are at least two major date related bugs in JDK 8. And, I've found differing behavior, bug or not, between JDK 8 and JDK 11/17. This class does its best to parse date strings. It does have a US-based date bias. Please open a ticket to fix this as needed. We can also add overrides via the parser config to manage customization of date formats. This code does not spark joy especially given the diffs in behavior between jdk versions. At some point, we should probably try joda or, heaven forfend, a pile of regexes.
