# IMessage.JMSTimestamp Property

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());

JMSTimestamp {get;}
