Placeholder Handler for ISO 8601 dates

[spalreddy]

It would be useful to have placeholder handler for ISO 8601 date formats.

i am considering making a pull request on this using java.time.format.DateTimeFormatter which is introduced in Java 8, thus making this library work only from java 8 onwards. Would it be acceptable ?

Sorry for the delay. The question isn't really that easy to answer :-)

I understand you want to use java.time over the mess that is SimpleDateFormat but bumping the Java requirement "just for that" feels a bit too much. OTOH it looks as if we'd start to alienate people who contribute by sticking with old APIs. Maybe we only change the requirements for the placeholders module? What do you think @krystiankaluzny ?

If we change the required version of Java we should make the next release 2.7.0 rather than a patch release.

Agree with you. Upgrading to Java 8 may need its own valid reasons than just this. Let me find sometime to make Pre Java 8 compatible pull request.

I'll deal with this together with #178 and xmlunit/xmlunit.net/#31

I've by now implemented a isDateTime placeholder, it is available in the 2.7.0-SNAPSHOT build I've published.
