本文整理了Java中java.time.LocalDateTime.atOffset()方法的一些代码示例，展示了LocalDateTime.atOffset()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。LocalDateTime.atOffset()方法的具体详情如下：
包路径：java.time.LocalDateTime
类名称：LocalDateTime
方法名：atOffset

LocalDateTime.atOffset介绍

[英]Combines this date-time with an offset to create an OffsetDateTime.

This returns an OffsetDateTime formed from this date-time at the specified offset. All possible combinations of date-time and offset are valid.
[中]将此日期时间与偏移量组合以创建OffsetDateTime。
这将返回从此日期时间在指定偏移量处形成的OffsetDateTime。日期时间和偏移量的所有可能组合均有效。

代码示例

protected Object convertTimestampWithZone(Column column, Field fieldDefn, Object data) {
  if (!(data instanceof DateTimeOffset)) {
    return super.convertTimestampWithZone(column, fieldDefn, data);
  }
  final DateTimeOffset dto = (DateTimeOffset)data;
  // Timestamp is provided in UTC time
  final Timestamp utc = dto.getTimestamp();
  final ZoneOffset offset = ZoneOffset.ofTotalSeconds(dto.getMinutesOffset() * 60);
  return super.convertTimestampWithZone(column, fieldDefn, LocalDateTime.ofEpochSecond(utc.getTime() / 1000, utc.getNanos(), offset).atOffset(offset));
}

代码示例来源：origin: apache/storm

int dateInt = (int) timestamp.toLocalDateTime().atOffset(ZoneOffset.UTC).toLocalDate().toEpochDay();
int localTimeInt = (int) (localTimestamp % DateTimeUtils.MILLIS_PER_DAY);
int currentTimeInt = (int) (currentTimestamp % DateTimeUtils.MILLIS_PER_DAY);

String input = "2015-08-21 03:15";
String offsetInfo = "GMT+05:30";

LocalDateTime ldt = 
 LocalDateTime.parse(input, DateTimeFormatter.ofPattern("uuuu-MM-dd HH:mm"));
ZoneOffset offset = 
 ZoneOffset.of(offsetInfo.substring(3)); // GMT-prefix needs to be filtered out

LocalDateTime result = 
 ldt.atOffset(offset).withOffsetSameInstant(ZoneOffset.UTC).toLocalDateTime();
System.out.print(result); // output: 2015-08-20T21:45
