The expected format is: yyyy-MM-dd'T'HH:mm'Z'. Maybe there should be a date and a datetime types. Or support for an alternative date-only format. Or we could just fix kirra-angular to send the date in the expected format.

Fixing so it too will accept yyy/MM/dd but that is really a bug in abstratt/kirra-ui#16.

Once we stop covering for kirra-angular, we could switch to using the new DateFormatter, which supports optional parts:

DateTimeFormatter formatter = new DateTimeFormatterBuilder().parseLenient().appendPattern(
    "yyyy-MM-dd['T'HH:mm[:ss[.SSS]]'Z']"
).toFormatter();

Fixed.
