Inconsistency with timezones

**Describe the bug**
There seem to be an inconsistency concerning timezones. Different parts of the API apparently use different timezones when using timestamps.

**To Reproduce**
Steps to reproduce the behavior:
1. Request a calendar object from the api [(Link)](https://alpaca.markets/docs/api-references/broker-api/calendar/#retrieving-the-market-calendar) and look at the response.
2. Request market data and compare the timestamps (and there respective price values) of the response with market data from a third source (in my case Tradingview).

**Expected behavior**
Both responses should use the same timezone for the timestamps of their response. As you see below, apparently they don't.

**Screenshots**
The requested calendar object seem to indicate that the UTC-4 timezone is used.

These are charts for symbol "QQQ" on 2nd Nov 2022. Comparing the requested market data and the data from tradingview (which in my case uses UTC +1), it seems like the market data from the Alpaca API uses timestamp from timezone UTC +0. Is that correct or am i missing something?
