Subject: [PATCH] + used std::chrono to set the expiration time of the ticket
 instead of hardcoded numbers, for clarity. isn't 24 hours a very long time?

+ set TimeSinceStartup from the new startup_timer, which starts counting when the .dll/.so is loaded in memory, currently using the amount of seconds, not sure if this is correct though
