Time Slider Hot Fix
Release Date: June 3, 2026
Type: Bug fix release
What's Fixed
Time slider broken on long summer days
Users with late summer dusks (roughly 9 PM or later depending on latitude) found the time slider completely unresponsive after updating to v2026.06.2, and clicking Play did nothing. The browser was also showing a tooltip "Please select a value that is no more than 21."
The cause was in the slider range calculation introduced in v2026.06.2. The arc extends slightly past dawn and dusk to give visual breathing room. The code was computing that extension by adding it to the dusk Unix timestamp and then converting the result to local-time minutes. For late-dusk days, dusk plus the extension crossed midnight into the next day, and the local-time conversion wrapped around, returning 21 (12:21 AM) as the slider maximum. With max set to 21 minutes, the slider was effectively dead.
The fix computes the extension in minutes directly and adds it to the already-converted dusk local time, avoiding the midnight wraparound entirely. A safety fallback was also added so that if the range calculation ever produces an invalid result, the slider falls back to the full 24-hour range instead of breaking.
