AWS::IoTEvents::AlarmModel AssetPropertyTimestamp
A structure that contains timestamp information. For more information, see TimeInNanos in the AWS IoT SiteWise API Reference.
You must use expressions for all parameters in AssetPropertyTimestamp
. The
expressions accept literals, operators, functions, references, and substitution
templates.
Examples
-
For literal values, the expressions must contain single quotes. For example, the value for the
timeInSeconds
parameter can be'1586400675'
. -
For references, you must specify either variables or input values. For example, the value for the
offsetInNanos
parameter can be$variable.time
. -
For a substitution template, you must use
${}
, and the template must be in single quotes. A substitution template can also contain a combination of literals, operators, functions, references, and substitution templates.In the following example, the value for the
timeInSeconds
parameter uses a substitution template.'${$input.TemperatureInput.sensorData.timestamp / 1000}'
For more information, see Expressions in the AWS IoT Events Developer Guide.
