How do you get a timestamp in ClojureScript?

Question

How can I get a timestamp in ClojureScript, similar to Unix's timestamp, a single number that represents the current time and date, as a number. I know that:

if (!Date.now) {
    Date.now = function() { return new Date().getTime(); }
}

can be used in Javascript but I want to know if there is a ClojureScript equivalant

Answer 1

You can use

(.getTime (js/Date.))

or you could also use now or epoch from cljs-time.

Answer 2

The most efficient way is this

(.now js/Date)

Other answers needlessly create a Date object.
