tldr.: Can construct somehow get server time? Or time from some other source?
I'm trying to rebuild my tamagotchi-like f2p game and add premium currency, that can boost and speed up procces of upgrading. I'm using similar system as clash of clans, upgrades that lasts for days when you are high level. My problem is, that anyone can manipulate their local time and effectively cheat and skip whole upgrade proess.
I was searching the forums but without any luck. There is plenty of info and plugins for using local time, but I can't use those if I want to monetize the game.
Thanks for any info
