It was my mistake, I figured out what the problem was. Unfortunately, your system (at least without a paid subscription) doesn't allow you to select a time zone in the settings. If a visitor is in a different region relative to the time at the desired point, you need to account for the time offset. Imagine a visitor from Europe, Asia, or even Australia. It's extremely difficult to see the desired readings at the desired time (especially in history), since your system simply assigns a time scale based on the visitor's IP address. And that's often not what they want! They want to see weather maps for a completely different time zone. They have to do some calculations in their head, which is extremely inconvenient. I recommend adding a time zone selection to the settings (even without a subscription) for calculating the time scale. Nowadays, many people around the world have begun to access the internet only through VPNs, and the exit point may be in a completely different place from where they actually are, which is even more confusing. It's better to have the time zone configured by the visitor themselves recorded in the cookie. They themselves decide which zone to base the time scale on. If they want to see the weather in Chicago, for example, but live in Europe, the simplest solution is obviously to set the time to the US time zone where Chicago is located, so that 6 PM in Chicago would be exactly 6 PM on your system's time scale.
I even came up with a way to make this more convenient for users. Add a special button next to or beside the timeline, or at the top, next to the settings icon, that will show the time on the timeline relative to the location visible at the center of the map (for example). If the Chicago metropolitan area is centered on the user's screen, for example, then their local time zone should obviously be used. If Tokyo is centered, then Tokyo time should be used. It's a bit more complicated when macro-scale is selected, but in that case, you can calculate based on the center of the screen display. Or, alternatively, make this configurable in the additional settings. Clearly specify the timeline's automatic alignment relative to what's shown on the screen.
But automatically shifting the timeline to the zone visible in the center of the screen is the most ideal solution, in my opinion, for all users. No need to rack your brains – the time on the screen is part of England, so it's automatically GMT. But if it's Australia, then it's Australian time.
