How it works

  1. Your browser reads the current moment from your device clock.
  2. It converts that moment to Europe/London time using the IANA timezone database built into modern browsers.
  3. The same moment is converted to America/Los_Angeles time.
  4. The UTC offsets of both cities are compared to calculate the exact hour difference.
  5. All three values — London time, Los Angeles time, and the offset — refresh every second.
  6. DST transitions for both cities are handled automatically, so the offset switches correctly each spring and autumn.
