With Jenkins Pipeline you can create a stage that uses sleep step. For example:

pipeline {
    agent none
    stages {
        stage('Wait') {
            agent { label 'wait-node' }
            steps {
                sleep time: 15, unit: "MINUTES"
            }
        }
    }
}

There's one drawback - your executor is blocked for all the wait time. To work around this in elegant way you can define a dedicated node (wait-node) with large enough number of executors to handle waiting stages (note - other stages may run on different nodes). This way actual executors aren't blocked and you can see all waiting jobs on Jenkins Dashboard.
