/**
* LocalTime is an immutable time class representing a time
* without a time zone.
*
* LocalTime implements the {@link ReadablePartial} interface.
* To do this, the interface methods focus on the key fields -
* HourOfDay, MinuteOfHour, SecondOfMinute and MillisOfSecond.
* However, all time fields may in fact be queried.
*
* Calculations on LocalTime are performed using a {@link Chronology}.
* This chronology will be set internally to be in the UTC time zone
* for all calculations.
*
*
Each individual field can be queried in two ways:
*
* getHourOfDay()
* hourOfDay().get()
*
* The second technique also provides access to other useful methods on the
* field:
*
* - numeric value
*
- text value
*
- short text value
*
- maximum/minimum values
*
- add/subtract
*
- set
*
- rounding
*
*
*
* LocalTime is thread-safe and immutable, provided that the Chronology is as well.
* All standard Chronology classes supplied are thread-safe and immutable.
