Just a quick report on my progress (no screenshots this time), I've managed to get a basic growing system working. Currently there are only 1 type of seeds, tree seeds, which when planted will eventually grow into actual trees to use to get logs. This growing system is one of my first big updates that will take advantage of the time system, and will later include different growth rates for different crops as well as different stages of growth. Stay tuned for more updates!
Interesting note, because of the way the tree growth is simulated, no players need to be online for anything to grow, the server only must be up. This way, you can plant stuff, leave, and come back later to harvest your crops.
