Usage.tsx

import { Label } from "@/components/ui/label";
import {
  Select,
  SelectContent,
  SelectItem,
  SelectTrigger,
  SelectValue,
} from "@/components/ui/select";
import { useId, useMemo } from "react";

function Component() {
  const id = useId();

  const timezones = Intl.supportedValuesOf("timeZone");

  const formattedTimezones = useMemo(() => {
    return timezones
      .map((timezone) => {
        const formatter = new Intl.DateTimeFormat("en", {
          timeZone: timezone,
          timeZoneName: "shortOffset",
        });
        const parts = formatter.formatToParts(new Date());
        const offset = parts.find((part) => part.type === "timeZoneName")?.value || "";
        const modifiedOffset = offset === "GMT" ? "GMT+0" : offset;

        return {
          value: timezone,
          label: `(${modifiedOffset}) ${timezone.replace(/_/g, " ")}`,
          numericOffset: parseInt(offset.replace("GMT", "").replace("+", "") || "0"),
        };
      })
      .sort((a, b) => a.numericOffset - b.numericOffset);
  }, [timezones]);

  return (
    <div className="space-y-2 min-w-[300px]">
      <Label htmlFor={id}>Timezone select</Label>
      <Select defaultValue="Europe/London">
        <SelectTrigger id={id}>
          <SelectValue placeholder="Select timezone" />
        </SelectTrigger>
        <SelectContent>
          {formattedTimezones.map(({ value, label }) => (
            <SelectItem key={value} value={value}>
              {label}
            </SelectItem>
          ))}
        </SelectContent>
