Java ResultSet 如何在 UTC 中获取时间戳

Question

数据库中有 UTC 数据，当我尝试获取数据时

java.util.Calendar cal = Calendar.getInstance();
cal.setTimeZone(TimeZone.getTimeZone("UTC"));
java.sql.Timestamp ts = resultSet.getTimestamp(PUBLISH_TIME);
cal.setTime(ts);

这有什么问题吗？

Answer 1

java.util.Calendar cal = Calendar.getInstance(); 
cal.setTimeZone(TimeZone.getTimeZone("UTC")); 
java.sql.Timestamp ts = resultSet.getTimestamp(PUBLISH_TIME, cal); 

这应该可以解决问题!
