Question: Advice for mocking datetime

[dalepotter]

• Package Name: azure-cosmos
• Package Version: 4.2.0
• Operating System: Ubuntu 20.04
• Python Version: 3.8

Describe the bug [May not be a bug] What is the advice for mocking date or datetime objects whilst interacting with Cosmos? Currently, attempts to fix the date are generating a CosmosHttpResponseError:

E           azure.cosmos.exceptions.CosmosHttpResponseError: (Forbidden) The authorization token is not valid at the current time. Please create another token and retry (token start time: Sat, 01 Jan 2000 00:00:00 GMT, token expiry time: Sat, 01 Jan 2000 00:15:00 GMT, current server time: Thu, 10 Nov 2022 13:08:20 GMT).

To Reproduce Steps to reproduce the behavior:

1. Install dependencies: $ pip install azure-cosmos pytest time-machine
2. Create a simple test script

import time_machine
from uuid import uuid4
from azure.cosmos import CosmosClient, PartitionKey, exceptions

@time_machine.travel("2000-01-01", tick=False)
def test_fixing_a_date():
    cosmos_client = CosmosClient(<URL HERE>, credential=<ACCESS KEY HERE>)
    # Set database
    try:
        database = cosmos_client.create_database(
            "ExampleDatabase"
        )
    except exceptions.CosmosResourceExistsError:
        database = cosmos_client.get_database_client(
            "ExampleDatabase"
        )

    # Set container
    try:
        container = database.create_container(
            id="ExampleContainer",
            partition_key=PartitionKey(path="/id")
        )
    except exceptions.CosmosResourceExistsError:
        container = database.get_container_client(
            "ExampleContainer"
        )
    except exceptions.CosmosHttpResponseError:
        raise

    item_added = container.upsert_item(
        {
            "id":  str(uuid4()),
            "example_key": "example_value"
        }
    )

    query_result = container.query_items(
        query=f'SELECT * FROM ExampleContainer c WHERE c.id="{item_added["id"]}"',
        enable_cross_partition_query=True
    )
    document = query_result.next()

    assert document["example_key"] == "example_value"

4. Run with pytest: $ pytest
5. Observe failure with stacktrace:

E           azure.cosmos.exceptions.CosmosHttpResponseError: (Forbidden) The authorization token is not valid at the current time. Please create another token and retry (token start time: Sat, 01 Jan 2000 00:00:00 GMT, token expiry time: Sat, 01 Jan 2000 00:15:00 GMT, current server time: Thu, 10 Nov 2022 13:08:20 GMT).

Expected behavior I would like some way of mocking date or datetime objects in unit tests that interact with Cosmos.
