A time without a time-zone _in the ISO-8601 calendar system, such as {@code 10:15:30}. !(p) {@code LocalTime} is an immutable date-time object that represents a time, often viewed as hour-minute-second. Time is represented to nanosecond precision. For example, the value "13:45.30.123456789" can be stored _in a {@code LocalTime}. !(p) This class does not store or represent a date or time-zone. Instead, it is a description of the local time as seen on a wall clock. It cannot represent an instant on the time-line without additional information such as an offset or time-zone. !(p) The ISO-8601 calendar system is the modern civil calendar system used today _in most of the world. This API assumes that all calendar systems use the same representation, this class, for time-of-day.
