Questions
Does it handle daylight saving?
Yes. Every clock is computed from the real time zone rules for the day you pick, so a call that works in March still works after the clocks change.
Can I share the setup?
The link updates as you change cities and the hour. Paste it and the other person sees the same clocks.
What counts as awake?
The green window is 8am to 10pm in every city you added. Adjust the hour to see how each clock reads.
The group chat knows where everyone is
SparkChat’s find-a-time poll and booking links already speak every member’s time zone, so the call lands at a sane hour for all of you.
