Get local time
By default, when you are setting up a new Date Object, it will return a date object with your browser's time
After creating a Date object, you can use below method to get the data you need
However, when you are developing an application, it's a common procedure that you will save and send the date in UTC time to support users in any timezone. In this case, you just need to specify UTC in your method, for example, getUTCTime()
Compate time
By using Date object, you can only use operator > , < , ≥, ≤. It doesn’t accept ===, == operator
A common approach we use in javascript is to convert it into million-second value and then compare two values. You can either use .getTime() or Date.parse(). It will return the same result
Convert date to local timestamp format
While reading in a Date object, you can use .tolocalString Intl.DateTimeFormat object to convert it into the datetime format in your locals.
- Date object api
The easiest way is to call the api .Below provide some example to show different type of api you can use
2. Intl.DateTimeFormat
//first create a new date object
const date = new Date();//convert the date object into Intel.DateTimeFormat object. without specifying any set up, it will format with local language. console.log(new Intl.DateTimeFormat.format(date))
//specify date format, you can format it with assgined language
console.log('format ir in US', new Intl.DateTimeFormat('en-US).format(date))
//add an option (object) to specify the format you want to present
const options = {
hour: 'numeric', minute:'numeric', second:'numeric',
timeZone: 'UTC',
timeZoneName: 'short'
}
console.log(new Intl.DateTimeFormat('en-GB', options).format(date))
