For example, the value for the <code>timeInSeconds</code> parameter can be <code>'1586400675'</code>.</p> </li> <li> <p>For references, you must specify either variables or input values. For example, the value for the <code>offsetInNanos</code> parameter can be <code>$variable.time</code>.</p> </li> <li> <p>For a substitution template, you must use <code>${}</code>, and the template must be in single quotes. A substitution template can also contain a combination of literals, operators, functions, references, and substitution templates.</p> <p>In the following example, the value for the <code>timeInSeconds</code> parameter uses a substitution template.</p> <p> <code>'${$input.TemperatureInput.sensorData.timestamp / 1000}'</code> </p> </li> </ul> <p>For more information, see <a href=\"https://docs.aws.amazon.com/iotevents/latest/developerguide/iotevents-expressions.html\">Expressions</a> in the <i>AWS IoT Events Developer Guide</i>.</p>",
