ETA Message

An ETA message is generated when the Drivers App calculates the ETA for stop.

The Drivers App can calculate the ETA for the next stop in the trip. Currently, there are 2 triggers for calculating the ETA.

Starting a trip -> This action triggers the ETA calculation of the first stop in the trip
Finishing a stop -> This action triggers the ETA calculation of the first unfinished stop in the trip

The data field of an ETA message consists of the properties described below.

Property	Nullable	Type	Description
foreignId	false	string	Contains the `foreignId` of the entity as provided in the trip message sent to the app
flag	false	string	Contains the `flag` of the entity as provided in the trip message sent to the app
eta	false	string	The ETA as an ISO 8601 formatted string
etaMillis	false	long	The ETA as a Unix timestamp (milliseconds)
calculatedAt	false	string	The moment the ETA was calculated as an ISO 8601 formatted string
calculatedAtMillis	false	long	The moment the ETA was calculated as a Unix timestamp (milliseconds)
