示例1: getTtl
import javax.jms.Message; //導入方法依賴的package包/類
/**
* Calculate TTL of given message from message
* expiration time and message timestamp.
* <p/>
* Returns the time the message expires, which is the sum of the time-to-live value
* specified by the client and the GMT at the time of the send
* EXP_TIME = CLIENT_SEND+TTL (CLIENT_SEND??)
* CLIENT_SEND time is approximately getJMSTimestamp() (time value between send()/publish() and return)
* TODO - check for correctness
*
* @param message calculate TTL for this message
* @return positive long number if TTL was calculated. Long.MIN_VALUE if error.
