could someone please check this works for me its in UTC and uk

// ----------------- UK CLOCK (device-proof) -----------------
function getUKNow() {
  const now = new Date(); // UTC baseline
  const y = now.getUTCFullYear();

  // BST: last Sunday in March -> last Sunday in October (UTC math)
  const bstStart = new Date(Date.UTC(y, 2, 31)); // Mar 31 UTC
  bstStart.setUTCDate(31 - bstStart.getUTCDay()); // last Sunday Mar
  const bstEnd = new Date(Date.UTC(y, 9, 31)); // Oct 31 UTC
  bstEnd.setUTCDate(31 - bstEnd.getUTCDay()); // last Sunday Oct

  const inBST = now >= bstStart && now < bstEnd;
  // UK time = UTC + (BST ? 1h : 0h)
  return new Date(now.getTime() + (inBST ? 1 : 0) * 3600 * 1000);
}
