I have two queries, fetching departure and return; I want the difference from it.
I do an outerjoin of the two resultsets, but the timestamp are repeated, how to resolve this?
Hello 
and welcome to the forum, @jandekock
Can you inspect that panel and view your raw, unformatted data? Or the raw response and query? I’m wondering if those timestamps are actually different on a sub-second level. Like this panel:
https://play.grafana.org/d/wC-4YLa7k/mja-checking-timestamps-for-subsonic-difference?orgId=1
hmmm, this is interesting indeed…
Can you share your query? And maybe one raw response from each of those two queries, where the timestamps appear the same? I ask because I’d like to try and reproduce this…
