references must be unspecified.
an array of Reference instances, each pointing to a causal parent
SpanContext. If specified,
fields.childOf must be unspecified.
a manually specified start time for the created Span object. The time should be specified in milliseconds as Unix timestamp. Decimal value are supported to represent time values with sub-millisecond accuracy.
