How do I get a Unix Timestamp in Clojure?

I want to know what the current timestamp is. The best I can do thus far is define my own function that does this:

(int (/ (.getTime (java.util.Date.)) 1000))

Is there a standard function for fetching the Unix timestamp with clojure?

Solution

  • Pretty much all JVM-based timestamp mechanisms measure time as milliseconds since the epoch - so no, nothing standard** that will give seconds since epoch.

    Your function can be slightly simplified as:

    (quot (System/currentTimeMillis) 1000)

    ** Joda might have something like this, but pulling in a third-party library for this seems like overkill.
