/**
* TimeOfDay is an immutable partial supporting the hour, minute, second
* and millisecond fields.
*
* NOTE: This class only supports the four fields listed above. Thus, you
* cannot query the millisOfDay or secondOfDay fields for example.
* The new LocalTime class removes this restriction.
*
* Calculations on TimeOfDay are performed using a {@link Chronology}.
* This chronology is set 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 -
hourOfDay().get()
* - text value -
hourOfDay().getAsText()
* - short text value -
hourOfDay().getAsShortText()
* - maximum/minimum values -
hourOfDay().getMaximumValue()
* - add/subtract -
hourOfDay().addToCopy()
* - set -
hourOfDay().setCopy()
*
*
* TimeOfDay is thread-safe and immutable, provided that the Chronology is as well.
* All standard Chronology classes supplied are thread-safe and immutable.
*
* @author Stephen Colebourne
* @author Brian S O'Neill

* @deprecated Use LocalTime which has a much better internal implementation and
* has been available since 1.3
