Is time at your android device correct? Checkit with atomic clock at GPS satellites by Smart GPS Time!
You can also synchronize time (only on rooted devices and BusyBoxinstalled) - to protect your security app specially designed so youcan see real command executed by super user (root).

If the app doesn't work for you, please get in touch with me. Ican't make the app better if you just leave a comment.
Please, rate the app if you like it. Thanks!
