Error parsing time data, genfromtxt related

Hey Developers. Could be a thredds issue.. Please close if not the right place. trying to find obs in Alaska for a project.. Specifically narrowed the variables required so I don't just get Anchorage..

Code:

metar_cat_url = 'http://thredds.ucar.edu/thredds/catalog/nws/metar/ncdecoded/catalog.xml?dataset=nws/metar/ncdecoded/Metar_Station_Data_fc.cdmr'

# parse the xml
metar_cat = TDSCatalog(metar_cat_url)

# what datasets are here? only one "dataset" in this catalog
dataset = list(metar_cat.datasets.values())[0]
ncss_url = dataset.access_urls["NetcdfSubset"]
ncss = NCSS(ncss_url)

#Bounding box for our query

#Utqiagvik @71.2741555,-156.8642725,12.47z
bb={'west':-170.0, 'east':-140.0,'north':75, 'south':60.0}

#create a new query for the server
query = ncss.query()

#Pass the bounding box through
query.lonlat_box(**bb)

#what measurements do we want?
query.variables('air_temperature', 'dew_point_temperature', 'inches_ALTIM',
                'wind_speed', 'wind_from_direction', 'precipitation_amount_24')

#                , 'cloud_area_fraction', 'weather',
#               'report_id', 'precipitation_amount_hourly', 'precipitation_amount_24')

#restrict to last 1200 hours.. that should be enough data
query.time_range(datetime(2018, 7, 1) , datetime(2018, 8, 7) )
query.accept('csv')

#run the query!
data = ncss.get_data(query)

Error:

When more vars added no time parsing error..

now when using

                                             datetime.utcnow() - timedelta(minutes=5))

I get
