如何将 a 转换ZonedDateTime
为 SQLTimestamp
并保留时区信息?我正在尝试采用 UTC 分区时间,将其转换为 a Timestamp
,然后将其转换回来,但是当我转换为 时Timestamp
,它会丢失时区信息,并且Timestamp
是使用我的本地时区创建的:
public static void main(String[] args) {
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("hh:mm a");
ZonedDateTime zdtUTC = ZonedDateTime.now(ZoneId.of("UTC"));
ZonedDateTime zdtNY = zdtUTC.withZoneSameInstant(ZoneId.of("America/New_York"));
ZonedDateTime zdtAZ = zdtUTC.withZoneSameInstant(ZoneId.of("America/Phoenix"));
ZonedDateTime zdtUK = zdtUTC.withZoneSameInstant(ZoneId.of("Europe/London"));
System.out.println(formatter.format(zdtUTC) + " in UTC zone");
System.out.println(formatter.format(zdtNY) + " in New York, NY");
System.out.println(formatter.format(zdtAZ) + " in Phoenix, AZ");
System.out.println(formatter.format(zdtUK) + " in London, UK");
Timestamp timestamp = Timestamp.from(zdtUTC.toInstant());
LocalDateTime converted = timestamp.toLocalDateTime();
ZonedDateTime convertedZdt = ZonedDateTime.of(converted, ZoneId.of("UTC"));
System.out.println(timestamp);
System.out.println(formatter.format(convertedZdt) + " in UTC zone");
}
06:33 PM in UTC zone
02:33 PM in New York, NY
11:33 AM in Phoenix, AZ
07:33 PM in London, UK
2017-05-07 14:33:06.745
02:33 PM in UTC zone
我需要做些什么来确保Timestamp
记录使用正确的时区信息?
