Chronograf dashboards display data adjusted to your local timezone. This can be annoying if you're trying to correlate timeseries data stored in UTC in InfluxDB with other databases. Unlike Grafana which provides an option to view in UTC, Chronograf doesn't have this option so far (but it will hopefully soon).
The good news is that you can trick Chrome (or Chromium based browsers) into thinking they are in whatever timezone you want. You probably want to use this with a separate profile so it doesn't mess with your other websites and extensions.
#!/bin/bash export TZ="Etc/GMT" PROFILE_DIR="some/path/to/new/chrome/profile" /usr/bin/google-chrome-stable --user-data-dir="$PROFILE_DIR"
EDIT: Chronograf 1.7.14 comes with the UTC/Local toggle. Fantastic work!
