Following is the code for clock/index.tsx to correct the double ampm AmPM issue in the obsidian-widgets clock widget 

```typescript
// src/Clock/index.tsx
import * as React from "react";
import { moment } from "obsidian";
import { WidgetType } from "src/types/Widgets";

const Clock = ({ settings }: ClockProps) => {
  const [time, setTime] = React.useState(moment().format("HH:mm:ss"));
  const [date, setDate] = React.useState(
    moment().format("dddd, MMMM DD, YYYY")
  );

  React.useEffect(() => {
    const clockInterval = setInterval(() => {
      const hideSeconds = settings.hideSeconds
        ? settings.hideSeconds !== "false"
        : false;
      const timeFormat =
        settings.format === "12hr"
          ? hideSeconds
            ? "hh:mm A"
            : "hh:mm:ss A"
          : hideSeconds
          ? "HH:mm"
          : "HH:mm:ss";

      setTime(moment().format(timeFormat));
      setDate(moment().format("dddd, MMMM DD, YYYY"));
    }, 100);

    return () => {
      clearInterval(clockInterval);
    };
  }, []);

  return (
    <div className="Clock_Face">
      <div className="Clock_Divider" />
      <div className="Clock__time-container">
        <div className="Clock__time">{time}</div>
      </div>
      <div className="Clock_Date">{date}</div>
      <div className="Clock_Divider" />
    </div>
  );
};

export default Clock;

export interface ClockSettings {
  type: WidgetType;
  format: "12hr" | "24hr";
  hideSeconds: string | null;
}

interface ClockProps {
  settings: ClockSettings;
}

Clock.defaultProps = {
  settings: {
    type: "clock",
    format: "24hr",
    hideSeconds: null,
  },
};

```
