Unix timestamp from date

OSCC · JavaScript, Date · Oct 19, 2020

Gets the Unix timestamp from a Date object.

  • Use Date.prototype.getTime() to get the timestamp in milliseconds and divide by 1000 to get the timestamp in seconds.
  • Use Math.floor() to appropriately round the resulting timestamp to an integer.
  • Omit the argument, date, to use the current date.
const getTimestamp = (date = new Date()) => Math.floor(date.getTime() / 1000);
getTimestamp(); // 1602162242
