Unix Timestamp in TypeScript

Look up the current epoch time and convert between Unix seconds and UTC dates in TypeScript.

Get the current timestamp

const nowSeconds: number = Math.floor(Date.now() / 1000);
console.log(nowSeconds);

Timestamp to date

const epochSeconds: number = 1_700_000_000;
console.log(new Date(epochSeconds * 1000).toISOString());

Date to timestamp

const parsedMilliseconds: number = Date.parse("2023-11-14T22:13:20Z");
console.log(Math.floor(parsedMilliseconds / 1000));

Open 1700000000 in the converter

How to use it

Copy the current-time example into your TypeScript environment to read Unix seconds.
Run the second example to display 1700000000 as a UTC date.
Run the last example to convert that date back into seconds.

The number type does not distinguish seconds from milliseconds. Name variables for their units and check Date.parse for NaN when accepting arbitrary text.
