Avoid two datetimes prepended to each New Relic Insights response

I’m not understanding why each NR response has time data appended. It’s causing duplicate rows

To reproduce: run an Insights query with no time dimension, such as
‘select count(*) from PageView facet pageUrl’

Expected:
Page URLs and counts are returned – one per URL.

Actual:
Two timestamps are returned per URL. The same results appear for each timestamp. The timestamps correspond to the first instance of the time range and the last instant of the time range.
