EDIT
Nothing wrong with the Sun integration; just me jumping to (wrong) conclusions. 
While helping someone else with a question about the Sun integration, I discovered that, on my system, it’s reporting the wrong times for sunrise and sunset. In fact, I run two, similarly configured instances of Home Assistant and both are reporting incorrect sunrise/sunset times (versions 2023.3.6 and 2023.3.3).
For my location (Eastern Time Zone) Home Assistant reports incorrect times for the attributes of sun.sun.
- Sunset (next_dusk) is a half-hour too late.
- Sunrise (next_dawn) is a half-hour too early.
System configuration of time zone and location (latitude/longitude) is correct. For comparison, I installed the Sun2 custom integration and it reports the correct time for sunrise and sunset.
The Sun2 integration reports the correct sunrise/sunset times but not the Sun integration (both are using the same, common data for local time, timezone, and lat/long). The time discrepancy is plus a half-hour for sunset and minus a half-hour for sunrise. 
Anyone have an idea why the Sun integration is misreporting the times?
NOTE
I’ve reported this in the GitHub Core repo but given that it’s currently 2 days prior to a major release (and there’s a backlog of over 2000 unresolved Issues) I’m hoping someone here might resolve this sooner than in GitHub (unless it’s an actual bug).
