日期和時間

沒有時區資訊的日期和時間

LocalDateTime dateTime = LocalDateTime.of(2016, Month.JULY, 27, 8, 0);
LocalDateTime now = LocalDateTime.now();
LocalDateTime parsed = LocalDateTime.parse("2016-07-27T07:00:00");

帶時區資訊的日期和時間

ZoneId zoneId = ZoneId.of("UTC+2");
ZonedDateTime dateTime = ZonedDateTime.of(2016, Month.JULY, 27, 7, 0, 0, 235, zoneId);
ZonedDateTime composition = ZonedDateTime.of(localDate, localTime, zoneId);
ZonedDateTime now = ZonedDateTime.now(); // Default time zone
ZonedDateTime parsed = ZonedDateTime.parse("2016-07-27T07:00:00+01:00[Europe/Stockholm]");

帶偏移資訊的日期和時間（即沒有考慮 DST 變化）

ZoneOffset zoneOffset = ZoneOffset.ofHours(2);
OffsetDateTime dateTime = OffsetDateTime.of(2016, 7, 27, 7, 0, 0, 235, zoneOffset);
OffsetDateTime composition = OffsetDateTime.of(localDate, localTime, zoneOffset);
OffsetDateTime now = OffsetDateTime.now(); // Offset taken from the default ZoneId
OffsetDateTime parsed = OffsetDateTime.parse("2016-07-27T07:00:00+02:00");
