PYTHON timestamp format is 2020-06-06T04:54:56.636664Z RFC3339Nano
JAVASCRIPT timestamp format is 1591419091.4805 to 1591419092.000035
PARENT TRACE - Adjust the parentDifference/spanDifference between .01 and .2 (1% and 20% difference) so the 'end timestamp's always shift the same amount (no gaps at the end)
TRANSACTIONS. body.contexts.trace.span_id is the Parent Trace. start/end here is same as the sdk's start_timestamp/timestamp, and start_timestamp is only present in transactions
To see a full span `firstSpan := body["spans"].([]interface{})[0].(map[string]interface{})``
