I am getting one error when try to get difference two dates.

I am getting expires date from backend. This is give me this Date- 2022-09-15T17:00:00.000+00:00

Now I have to difference this date to now date.

I try it i this way-

 const expires = new Date("2022-09-15T17:00:00.000+00:00");
 const now = new Date();
 const expiryTimestamp = new Date((+expires - +now) / (1000 * 60 * 60 * 24))
 console.log(expiryTimestamp);

But It is not working. In console I find this -

Thu Jan 01 1970 06:00:00 GMT+0600 (Bangladesh Standard Time)

But Why it print 1970.

I also try without-

const expires = new Date(flash?.expires);
const now = new Date();
const expiryTimestamp = new Date((+expires - +now)))
console.log(expiryTimestamp);

But not working.

What do you expect `epiryTimestamp` to be? – evolutionxbox Sep 15 '22 at 09:05
The issue is because you're putting the result, which a floating point value of the differece in days, in a `new Date()`. JS Dates start at the epoch, so you're effecting saying `1970-01-01 + diff`. Remove the last `Date()` object and your code works. See the duplicate for more details. – Rory McCrossan Sep 15 '22 at 09:05
@evolutionxbox, expiryTimestamp should be date formate – Md Ali Sep 15 '22 at 09:07
So what do you think the value _should be_? – evolutionxbox Sep 15 '22 at 09:09
Can you see value print `1970` but why, here time is `2022`. – Md Ali Sep 15 '22 at 09:11
@RoryMcCrossan, Hello, can you describe more. I actually stacking. – Md Ali Sep 15 '22 at 09:28
There's nothing I could add which isn't already described in the duplicate – Rory McCrossan Sep 15 '22 at 09:34
