Hi,
I have my home assistant installed and configured in a time zone UTC+1.
Everything is fine as long as I’m running the front-end in the same time zone.
At the moment, I’m UTC+11 and all graphs (mostly apexcharts based) report wrongly.
My basic understanding is that the time zone where I run the lovelace front-end is the reference for apexcharts, while only the time zone of my home makes sense.
Is there a way to tell lovelace or apexcharts to consider UTC+1 instead UTC+11 ?
Thanks !
I have no ready solution but a suggestion, you could try (!) to add a templated ‘offset’ to the apexcharts where the value would be pulled from a helper that shows the +11 or whatever.
Now, apexcharts probably does not allow templates but there you could try through adding card-templater…which does not always work. Possibly best to raise this here: ApexCharts card - A highly customizable graph card - Share your Projects! / Dashboards & Frontend - Home Assistant Community (home-assistant.io)
So, was intriguing and got it to work with a helper…forget about the details of the card and sensor… you need to try this out (so am I) 
type: custom:card-templater
card:

let res = []; for (const [key, value] of
Object.entries(entity.attributes.forecast.result)) {
res.push([new Date(key).getTime(), value]);
} return res
