Examples of ZoneInfo

sun.util.calendar.ZoneInfo
ZoneInfo is an implementation subclass of {@link java.util.TimeZone TimeZone} that represents GMT offsets anddaylight saving time transitions of a time zone.
The daylight saving time transitions are described in the {@link #transitions transitions} table consisting of a chronologicalsequence of transitions of GMT offset and/or daylight saving time changes. Since all transitions are represented in UTC, in theory, ZoneInfo can be used with any calendar systems except for the {@link #getOffset(int,int,int,int,int,int) getOffset}method that takes Gregorian calendar date fields.
This table covers transitions from 1900 until 2037 (as of version 1.4), Before 1900, it assumes that there was no daylight saving time and the getOffset methods always return the {@link #getRawOffset} value. No Local Mean Time is supported. If aspecified date is beyond the transition table and this time zone is supposed to observe daylight saving time in 2037, it delegates operations to a {@link java.util.SimpleTimeZone SimpleTimeZone}object created using the daylight saving time schedule as of 2037.
The date items, transitions, GMT offset(s), etc. are read from a database file. See {@link ZoneInfoFile} for details. @see java.util.SimpleTimeZone @since 1.4
