I noticed tonight that when imputing the start time = 2021-10-16 UT-5, the output will be +5. The issue just began today as I noticed bad ephemerides for 2019 XS all of a sudden. Below is the output for 2021 TG14 as an example. It appears okay when simply generating an ephemeris for UT and not local time. I contacted Horizons concerning this weirdness.
