Gets the message timestamp as a long.

The JMSTimestamp header field contains the time a message was handed off to be sent. It is not the time the message was actually transmitted, because the actual send may occur later due to transactions or other client-side queueing of messages.

When a message is sent, JMSTimestamp is ignored. When the Send or Publish method returns, it contains a time value somewhere in the interval between the call and the return.

The value is in the format of a normal millis absolute time value in the Java programming language, which is the difference, measured in milliseconds, between the a given time and midnight, January 1, 1970 UTC.

// Example:  Converting the current .NET time to Java millis time
DateTime baseTime = new DateTime(1970, 1, 1, 0, 0, 0);
DateTime utcNow = DateTime.UtcNow;
long timeInMillis = (utcNow.Ticks - baseTime.Ticks)/10000;
Console.WriteLine(timeInMillis);

// Example:  Converting Java millis time to .NET time
DateTime baseTime = new DateTime(1970, 1, 1, 0, 0, 0);
long utcTimeTicks = (timeInMillis * 10000) + baseTime.Ticks;
DateTime utcTime = new DateTime(utcTimeTicks, DateTimeKind.Utc);
Console.WriteLine(utcTime);
Console.WriteLine(utcTime.ToLocalTime());
