You only have to send a datetime stamp and at least one field. The datetime stamp can be in many formats such as epoch, ISO 8601, or MySQL time. If the datetime includes a GMT/UTC offset, we will use that to properly import the data. If your datetime stamps do not have a GMT / UTC offset, you can specify a time zone that the data was logged in.
