We are publishing event to Azure Event Grid. Event containse field with datetimeoffset format

timestamp": "2019-07-26T16:59:57-05:00"

The message consumer is azure function with EventGridTrigger

    [Function("Test")]
    public async Task<string> RunAsync([EventGridTrigger] string msg)
    {
        ...
    }

Azure function is been receiving message with incorrect offset

"timestamp": "2019-07-26T23:59:57+02:00"

Axpected result: reseived event timestamp field with date time offset must be equal to published

Actual result: reseived event timestamp field with date time offset has wrong offset (expected -05:00 actual +02:00)

"timestamp": "2019-07-26T23:59:57+02:00"

Rem:

• we tested events schemes: EventGridSchema and CloudEventSchemaV1_0
• we tested different bindings: string, CloudEvent, EventGridEvent, JSON serializable type

Rem:

• at the same time if we redirect data from event grid to service bus the message has correct data.
• based on this, we can conclude that the problem concerns EventGridTrigger as a part of azure function
