Date part to milliseconds.
I've this time
2023-05-25T11:18:45.752Z . How do I get only the date part and change it to milliseconds. I know I can change the whole datetime to seconds by
But this takes the full datetime.8 Replies
You pass the date string into the
new Date() constructor. Also, the .getTime() method return the number of milliseconds since January 1, 1970, UTC not the number of seconds.
So you'd do new Date("2023-05-25T11:18:45.752Z").getTime()
Or you could do Date.parse("2023-05-25T11:18:45.752Z").
Either way, you'd get the returned value of 1685013525752 ms since Epoc 0Ok understood. But is
.getTime() the right thing to use. I want my given time to be changed into milliseconds. As you said it gives the number of milliseconds since Jan 1, 1970.That's what timestamps are, number of (m)s since Jan 1 1970. What are you wanting to do?
I just want them to be changed to milliseconds. I got a function where I'm comparing dates that's why need the whole date into milliseconds. But it's working for me so I got no complains.
Just a question what if the date value is less than jan 1 1970.
Then it's a negative number
But if you want to change a time to ms, then use either of the two methods I shared above. In JS all timestamps are in ms so there's no conversion or hidden trick needed.
If you want less-precise than ms that's when you start making functions to do maths
ok got it. Thank you 💛
