Hello Massimo
I understand you. An imperfect way to solve this would be to include a encrypted file with install date and last run end somewhere hidden in the computer. With this the user would have to be careful to set the computer time a second after last run end .
Eh... by experience, an hidden file is the easiest stuff to find
For windows there's the registry, you can hide quite many things there, but for linux ?
Mhhhh... maybe I've got a nicer idea, which could be combined with the rest.
Access to a time server could do the job. It could be triggered randomly, and accept some failures, if the user isn't connected to the net.
