Alarm
A structure that contains timestamp information. For more information, see TimeInNanos in the 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 Developer Guide.
