Hi James,
It looks like the most recent observation posted to the ETD for K2-34 b is ~20 minutes late. I'm not familiar enough with ETD to know if the ephemeris they provide considers the BJD_TDB offsets. Maybe your measurement is good as long as your observatory computer clock was accurate when the observations were taken? In any event, it appears the ephemeris for K2-34 b on ETD is a bit stale relative to the last three measurements that were uploaded.
