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

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