Joda Time, parse hours and clockhours at the same time

I want to have a DateTime Parser that can parse a time that is either in "normal" hours or in clockhours. Means that I can have 00:00:00 or 24:00:00 at the same time. Further clockhour is only allowed for midnight. Means 24:00:01 is not allowed. This must be expressed as 00:00:01. Is this somehow achievable? My parser currently does not respect clockhours:

//The formatter for the timezone
DateTimeFormatter timezoneFormatter = new DateTimeFormatterBuilder().appendTimeZoneOffset(null, true, 2, 2)
            .toFormatter();
//The formatter for the fractional (3 digit) seconds
DateTimeFormatter fractionalSecondsFormatter = new DateTimeFormatterBuilder().appendLiteral('.')
            .appendFractionOfSecond(3, 3).toFormatter();

// Here a parser is created that parses a string of the form HH:mm:ss. Further the string may have
// 3 digit fractional seconds (with a dot as prefix) and may have a timezone.
DATE_TIME_PARSER = new DateTimeFormatterBuilder().appendHourOfDay(2).appendMinuteOfHour(2).appendSecondOfMinute(2)
            .appendOptional(fractionalSecondsFormatter.getParser()).appendOptional(timezoneFormatter.getParser())
            .toFormatter();

Would be greate if someone could help me.

Best regards, Florian

Joda-Time does not support parsing of 24:00. If you want to parse that you'll need to implement DateTimeParser yourself and intergrate it using DateTimeFormatterBuilder.

Clock hour 24 would equate to 23:00. Using the format kk:mm:ss 24:00:01 would be allowed. So in that sense 24:00:00 is never equal to 00:00:00.
