[threeten-dev] Midnight at the end of day

[Rosczak, Jan]

Hello,

thanks for the quick answer. That partly solves my problem, but still for a value of "2012-12-03T24:00" after parsing I do not know if "2012-12-04T00:00" or "2012-12-03T24:00" was meant, which makes a difference for us. Why don't I get an excess day in that case too?

Thanks
Jan

There is no class in JDK8 that will support holding 24:00. You can create your own implementing TemporalAccessor or Temporal if you want one. (ISO-8601 is a data interchange format, whereas the classes aim to be clearly defined)

The parsing mechanism does support parsing 24:00. See
http://download.java.net/jdk8/docs/api/java/time/format/DateTimeFormatter.html#parsedExcessDays--
Similarly, formatting will output any value, so if HOUR_OF_DAY returns 24, then that is what will be output.

The ISO 8601 norm says that for the field hour, the valid values are 00-24, where 24 is only used to denote midnight at the end of a calendar day.
