17:38:29 net.minecraft.server.MinecraftServer Can't keep up! Did the system time change, or is the server overloaded? Running 3694ms behind, skipping 73 tick(s)

and then it crashes. i've tried uninstalling minecraft and java multiple times. i have 1gb of ram dedicated, which should be enough as far as i know, and intel gpu. drivers are updated. this is on a singleplayer world. help?

Does it crash, or does it just close? If it gives you a crash report, you may want to give that. What kind of specs does your computer have?

EDIT: Does this happen in multiplayer?
