Coding vs Node-RED Flow Everyone can quickly develop the REST API which returns date and time through flow and UI settings. const moment = require('moment-timezone'); const express = require('express'); const app = express(); const port = 1880; app.get('/moment', (req, res) => { moment.locale('zh-cn'); var tmp = moment().tz('Asia/Shanghai'); res.send(tmp.format('LLLL')); }); app.listen(port, () => { console.log(`Running on ${port}`); }); Code Flow and settings
