How to get build time stamp from Jenkins build variables?

Question

How can I get build time stamp of the latest build from Jenkins? I want to insert this value in the Email subject in post build actions.

Answer 1

Try use Build Timestamp Plugin and use BUILD_TIMESTAMP variable.

Answer 2

I know its late replying to this question, but I have recently found a better solution to this problem without installing any plugin. We can create a formatted version number and can then use the variable created to display the build date/time. Steps to create: Build Environment --> Create a formatted version number:

• Environment Variable Name: BUILD_DATE

• Version Number Format String: ${BUILD_DATE_FORMATTED}

thats it. Just use the variable created above in the email subject line as ${ENV, var="BUILD_DATE"} and you will get the date/time of the current build.

If you want add a timestamp to every request from browser to jenkins server. You can refer to the jenkins crumb issuer mechanism, and you can hack the /scripts/hudson-behavior.js add modify here. so it will transform a timestamp to server.

    /**
     * Puts a hidden input field to the form so that the form submission will have the crumb value
     */
    appendToForm : function(form) {
        // add here. ..... you code
        if(this.fieldName==null)    return; // noop
        var div = document.createElement("div");
        div.innerHTML = "<input type=hidden name='"+this.fieldName+"' value='"+this.value+"'>";
        form.appendChild(div);
    }

You can use the Jenkins object to fetch the start time directly

Jenkins.getInstance().getItemByFullName(<your_job_name>).getBuildByNumber(<your_build_number>).getTime()
