What time zone am I in?

Find your time zone and its next scheduled daylight saving change, if any.

Your coordinates are sent to ParseAPI for the lookup.

Use it in your app

GET /point?lat=39.74&lon=-104.99

GET /time/America/Denver?deep=true

Point returns the IANA timezone and administrative location. Pass that zone to Time with deep=true for the local clock and next scheduled offset change. This tool makes those two calls, each using one pooled request on every plan.

QUESTIONS

How does it know my zone?
With your permission, your browser sends coordinates to ParseAPI to find the time zone at that point. Those coordinates are included in request logs.
Why not just use my clock?
Your device clock reflects its settings, not the ground you are standing on. Near a zone border, after travel, or on a misconfigured machine the two disagree.
What is the daylight saving line?
The next scheduled clock change for your zone, straight from the IANA rules. Zones that never change simply do not show one.
Can I do this from code?
Yes. GET /point?lat={lat}&lon={lon} returns timezone, country, state, and district. Pass the returned zone to /time/{timezone}?deep=true for local time and the next clock change. Each call uses one pooled request on every plan.
