> RT, 当alpha与omega所在节点的时间不同步时，分布式事务会被异常aborted。检查代码发现alpha侧创建TxEvent时用到了omega侧传过来的时间戳。
> {code:java}
> @Override
> public void onTxEvent(GrpcTxEvent message, StreamObserver<GrpcAck> responseObserver) {
>   boolean ok = txConsistentService.handle(new TxEvent(
>       message.getServiceName(),
>       message.getInstanceId(),
>       new Date(message.getTimestamp()),  // 这里用到了omega侧传过来的时间戳
>       message.getGlobalTxId(),
>       message.getLocalTxId(),
>       message.getParentTxId().isEmpty() ? null : message.getParentTxId(),
>       message.getType(),
>       message.getCompensationMethod(),
>       message.getTimeout(),
>       message.getRetryMethod(),
>       message.getRetries(),
>       message.getPayloads().toByteArray()
>   ));{code}
>  
> 这里感觉可以直接用收到TxEvent的时间，即*new Date()*即可。
