Time Zone Settings

The runtime environment of cloud functions maintains UTC time, which is the time in the 0 time zone, resulting in an 8-hour time difference from Beijing time.

You can use time processing libraries or packages in programming languages (such as moment-timezone) to identify UTC time and convert it to Beijing time (UTC+8).

Note: The current function version supported by Cloud Development is Node 10, which cannot specify the time zone by setting the environment variable TZ=Asia/Shanghai (Node 15+ versions support this).

Reference code:

const moment = require("moment-timezone"); // Requires specifying and installing dependencies in package.json

exports.main = async (event, context) => {
  // javascript date
  console.log(new Date()); // 2021-03-16T08:04:07.441Z (UTC+0)
  console.log(moment().tz("Asia/Shanghai").format()); // 2021-03-16T16:04:07+08:00 (UTC+8)
};
