How do I run a Jenkins job where user can enter a date and time value?

Question

I wanted to run a jenkins job by accepting a date and time field (in format YYYY-MM-DD hh:mm) from user.

Answer 1

Use parameterized build to get user input at the start of your job. https://wiki.jenkins.io/display/JENKINS/Parameterized+Build

Sample pipeline

pipeline {
    agent {label 'slave'}
    parameters {
        string(name: 'DateTime', defaultValue: '', description: 'Enter date & time in format YYYY-MM-DD hh:mm')
    }
    stages {
        stage('Build') {
            steps {
                // Build
            }
        }
    }
  }
