Note:
- The Expiry field in the MQMD is a special case:
- An INTEGER value represents an expiry interval in tenths of a second. If the Expiry field is set to -1, it represents an unlimited expiry interval (that is, the message never expires) If the Expiry field is a positive INTEGER, it represents an expiry interval of that number of tenths of a second (for example, if it is set to 4, it represents 4 tenths of a second, if it is set to 15, it represents one and a half seconds).
- A GMTTIMESTAMP value represents a specific expiration time.
If Expiry contains a GMTTIMESTAMP in the past, or an INTEGER of less than 1 (excluding -1), it is set to the value 1 (one tenth of a second, the minimum value).
