/**
* Parses a datetime from the given text, at the given position, saving the
* result into the fields of the given ReadWritableInstant. If the parse
* succeeds, the return value is the new text position. Note that the parse
* may succeed without fully reading the text and in this case those fields
* that were read will be set.
* <p>
* Only those fields present in the string will be changed in the specified
* instant. All other fields will remain unaltered. Thus if the string only
* contains a year and a month, then the day and time will be retained from
* the input instant. If this is not the behaviour you want, then reset the
* fields before calling this method, or use {@link #parseDateTime(String)}
* or {@link #parseMutableDateTime(String)}.
* <p>
* If it fails, the return value is negative, but the instant may still be
* modified. To determine the position where the parse failed, apply the
* one's complement operator (~) on the return value.
* <p>
* This parse method ignores the {@link #getDefaultYear() default year} and
* parses using the year from the supplied instant based on the chronology
* and time-zone of the supplied instant.
* <p>
* The parse will use the chronology of the instant.
