This answer below shows another method using "regexp feature of the Description Setter Plugin" which solved my problem as I could not install new plugins on Jenkins due to permission issues:

You can use the Jenkins object to fetch the start time directly Jenkins getInstance   getItemByFullName  lt your job name gt   getBuildByNumber  lt your build number gt   getTime    also answered it here  https   stackoverflow com a 63074829 1968948

BUILD ID used to provide this information but they changed it to provide the Build Number since Jenkins 1 597  Refer this for more information  You can achieve this using the Build Time Stamp plugin as pointed out in the other answers  However  if you are not allowed or not willing to use a plugin  follow the below method  def BUILD TIMESTAMP   null withCredentials  usernamePassword credentialsId   JenkinsCredentials   passwordVariable   JENKINS PASSWORD   usernameVariable   JENKINS USERNAME          sh script   quot curl https     JENKINS USERNAME    JENKINS PASSWORD   lt JENKINS URL gt  job  lt JOB NAME gt  lastBuild buildTimestamp quot   returnStdout  true  trim      println BUILD TIMESTAMP  This might seem a bit of overkill but manages to get the job done  The credentials for accessing your Jenkins should be added and the id needs to be passed in the withCredentials statement  in place of  JenkinsCredentials   Feel free to omit that step if your Jenkins doesn t use authentication

One way this can be done is using shell script in global environment section  here  I am using UNIX timestamp but you can use any shell script syntax compatible time format   pipeline        agent any      environment           def BUILDVERSION   sh script   echo  date   s    returnStdout  true  trim              stages           stage  Awesome Stage                 steps                   echo  Current build version     BUILDVERSION

NOTE  This changed in Jenkins 1 597  Please see here for more info regarding the migration  You should be able to view all the global environment variables that are available during the build by navigating to https    lt your-jenkins gt  env-vars html   Replace https    lt your-jenkins gt   with the URL you use to get to Jenkins webpage  for example  it could be http   localhost 8080 env-vars html    One of the environment variables is    BUILD ID     The current build id  such as  2005-08-22 23-59-59   YYYY-MM-DD hh-mm-ss    If you use jenkins editable email notification  you should be able to use   ENV  var  BUILD ID   in the subject line of your email

Try use Build Timestamp Plugin and use BUILD TIMESTAMP variable

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     lt input type hidden name    this fieldName    value    this value    gt            form appendChild div
