What TimeSlotSync does
TimeSlotSync is a time zone meeting planner and world clock for teams that are spread across countries. Use it as a time zone converter to compare cities, as a world clock to check where someone's day currently stands, or as a meeting time matcher to find the overlap windows that work for two to six people at once.
Unlike a plain offset table, the planner scores each candidate window by how much unsociable time it asks of each participant, defaults to business days rather than any technically valid slot, and warns you when a daylight saving change falls between today and the meeting you are planning. Nothing is stored on a server: your plan is encoded into the share link you generate, so you can send it to colleagues and everyone sees the same windows in their own local time.
