Demo

http://pvoznyuk.github.io/react-live-clock

Usage

import React  from 'react';
import Clock from 'react-live-clock';

exports default class MyComponent extends React.Component {
    render() {
        <Clock format={'HH:mm:ss'} ticking={true} timezone={'US/Pacific'} />
    }
}

Outputs:

<time>10:15:34</time>

** Shows current time for 'US/Pacific' timezone and updates every second

React Native

React Native requires that you wrap text in a <Text> like this:

import { Text, View } from "react-native";
import Clock from "react-live-clock";

export default function ClockPage() {
  return (
    <View>
      <Text>Clock page</Text>
      <Clock element={Text} />
    </View>
  );
}

If you don't you will get the error Invariant Violation: Text strings must be rendered within a <Text> component.
