| Use the date from the internet and not from the local computer. They cannot change that one. |

Thanks Bob Roos :thank you:
but my application doesn't require internet connection, so he can use it without connecting to internet |

one simple way:
STORE the date the user starts using your application (of course)
STORE EACH LAST DATE, IF GREATER than the first one
And of course, if date is suddenly SMALLER than the last one, either your user invented a time machine, or he changed the date of the computer.... and then you block |
