Timestamp generation in Postman - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to get the current timestamp in milliseconds.

Postman

var timestamp = [1]();

Drag options to blanks, or click blank then click option'

AtimeNow

BgetTime

Cnew Date

DDate.now

💡 Hint

Common Mistakes

Using new Date() without calling getTime() returns a Date object, not a timestamp.

Using a non-existent function like timeNow.

Date.now() returns the current timestamp in milliseconds since January 1, 1970.

2fill in blank

medium

Complete the code to convert a Date object to a timestamp in milliseconds.

Postman

var timestamp = new Date().[1]();

Drag options to blanks, or click blank then click option'

AgetTime

Bnow

CtoISOString

DvalueOf

Attempts:

💡 Hint

Common Mistakes

Using now() on a Date instance causes an error.

Using toISOString() returns a string, not a timestamp.

getTime() returns the timestamp in milliseconds from a Date object.

3fill in blank

hard

Fix the error in the code to get the current timestamp in seconds.

Postman

var timestamp = Math.floor(Date.[1]() / 1000);

Drag options to blanks, or click blank then click option'

Anow

BtimeNow

CgetTime

DcurrentTime

💡 Hint

Common Mistakes

Using getTime() as a static method of Date causes an error.

Using non-existent functions like timeNow or currentTime.

Date.now() returns the current timestamp in milliseconds. Dividing by 1000 and using Math.floor gives seconds.

4fill in blank

hard

Fill both blanks to create a timestamp string in ISO format and get its timestamp in milliseconds.

Postman

var isoString = new Date().[1]();
var timestamp = new Date(isoString).[2]();

Drag options to blanks, or click blank then click option'

AtoISOString

BgetTime

Cnow

DtoString

Attempts:

3 left

💡 Hint

Common Mistakes

Using now() instead of toISOString() for string conversion.

Using toString() returns a non-ISO string.

toISOString() converts the date to ISO string format.
getTime() converts the ISO string back to milliseconds timestamp.

5fill in blank

hard

Fill all three blanks to create a UNIX timestamp in seconds from a Date object.

Postman

var date = new Date();
var milliseconds = date.[1]();
var seconds = Math.[2](milliseconds / [3]);

Drag options to blanks, or click blank then click option'

AgetTime

Bfloor

C1000

Dnow

Attempts:

3 left

💡 Hint

Common Mistakes

Using now() on Date instance causes error.

Using Math.round instead of Math.floor changes the result.

Dividing by 60 or 100 instead of 1000.

getTime() gets milliseconds from the Date.
Math.floor() rounds down to whole seconds.
1000 converts milliseconds to seconds.
