        From the python documentation:
            > Naive datetime instances are assumed to represent local time
        Therefore, calling "since.timestamp()" will get the UTC timestamp, after applying the
        transformation from local timezone to UTC.
        This works for timezones UTC+ since then the result will contain trades from a few hours
        instead of from the last 5 seconds, however fails for UTC- timezones,
        since we're then asking for trades with a "since" argument in the future.
