title: Get Timestamp
|
|
---
|
|
You can use `Date.now()` to get the current timestamp in milliseconds.
|
|
|
|
You can easily convert the timestamp to seconds like this: `Math.floor(Date.now() / 1000)`
|
|
|
|
If your browser does not support `Date.now()`, you can use `new Date().getTime()` to get the timestamp in milliseconds.
|
|
|
|
Unix Timestamp is number of seconds elapsed since 01/01/1970, 00:00:00 UTC. The Unix timestamp will break on 01/19/2038.

|
For older browsers, we can use:
|
|
```js
|
|
if (!Date.now) {
|
|
Date.now = function now() {
|
|
return new Date().getTime();
|
|
};
|
|
}
|
|
```
|
