/**
    Field indices to be passed to various <type>XCalendar</type> methods.

    <p> Field is writable only if marked both Get/Set. </p>

    <p> ZONE_OFFSET and DST_OFFSET cooperate such that both values are added,
    for example, ZoneOffset=1*60 and DstOffset=1*60 results in a time
    difference of GMT+2. The calculation in minutes is
    GMT = LocalTime - ZoneOffset - DstOffset </p>

    <p> With introduction of ZONE_OFFSET_SECOND_MILLIS and
    DST_OFFSET_SECOND_MILLIS the exact calculation in milliseconds is
    GMT = LocalTime
        - (ZoneOffset*60000 + ZoneOffsetMillis * sign(ZoneOffset))
        - (DstOffset*60000 + DstOffsetMillis * sign(DstOffset))
