在
Java 8中,我想将datetime从UTC转换为ACST(UTC 9:30).
输入 – > 2014-09-14T17：00：00 00:00
输出 – > 2014-09-15 02:30:00
String isoDateTime = "2014-09-14T17:00:00+00:00";
LocalDateTime fromIsoDate = LocalDateTime.parse(isoDateTime,DateTimeFormatter.ISO_OFFSET_DATE_TIME);
ZoneOffset offset = ZoneOffset.of("+09:30");
OffsetDateTime acst = OffsetDateTime.of(fromIsoDate,offset);
System.out.println(acst.toString()); // 2014-09-14T17:00+09:30
System.out.println(acst.format(DateTimeFormatter.ISO_OFFSET_DATE_TIME)); // 2014-09-14T17:00:00+09:30
为什么不执行偏移？
解决方法
尝试：
String isoDateTime = "2014-09-14T17:00:00+00:00";
ZonedDateTime fromIsoDate = ZonedDateTime.parse(isoDateTime);
ZoneOffset offset = ZoneOffset.of("+09:30");
ZonedDateTime acst = fromIsoDate.withZoneSameInstant(offset);
System.out.println("Input: " + fromIsoDate);
System.out.println("Output: " + acst.format(DateTimeFormatter.ISO_OFFSET_DATE_TIME));
输出：
Input: 2014-09-14T17:00Z Output: 2014-09-15T02:30:00+09:30
