We can use following steps to ensure that date / time also get stored along with history commands:

  1. Create file '/etc/profile.d/history.sh'
  2. Add following lines to file: 
    #!/bin/bash
    

    

    HISTTIMEFORMAT="%y %m %d %T "
    

    HISTSIZE=100000
    

    HISTFILESIZE=100000
    

    export HISTTIMEFORMAT HISTSIZE HISTFILESIZE
  3. chmod +x /etc/profile.d/history.sh


Note: Do not make mistakes in this file like adding 'exit 0'. All /etc/profile.d scripts are run directly from new shell which is getting spawned. Making mistakes in profile.d scripts may make shell inaccessible. Hence never experiment with new profile.d scripts on servers on which you have only remote access, like hosting services, cloud, etc. In case some mistake is already done you can refer to Deleting shell start-up scripts remotely without executing them, to make system work again.
