add minutes to timestamp- most efficient way
提问by Lisa
I have to write a java code to add minutes(delayminutes) to a timestamp(tmpTimeStamp). This is what I have. I was wondering if this is an efficient way to do this or if there is a better way.
我必须编写一个java代码来将分钟（延迟分钟）添加到时间戳（tmpTimeStamp）。这就是我所拥有的。我想知道这是否是一种有效的方法，或者是否有更好的方法。
long t=tmpTimeStamp.getTime();
long m=delayMinutes*60*1000;
targetDeliveryStamp= new Timestamp(t+m);

That's pretty good. You can be slightly more efficient and avoid object construction overhead if you can reuse your temporary Timestamp:
这很好。如果您可以重用临时时间戳，则可以稍微提高效率并避免对象构造开销：
tmpTimeStamp.setTime(tmpTimeStamp.getTime() + TimeUnit.MINUTES.toMillis(delayMinutes));
