/**
|
|
* A time without time-zone in the ISO-8601 calendar system,
|
|
* such as `10:15:30`.
|
|
*
|
|
* {@link 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 {@link LocalTime}.
|
|
*
|
|
* It 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.
|
|
*
|
|
* 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.
