Ok so I do not know which log you want exactly there are three different ones. One is from starting up the server, Another is just three lines saying can't keep up! Did the system time change, or is the server overloaded? Running ---ms behind, Skipping --- Ticks. And then the shutdown log. If all you need is the shutdown log I posted everything that appeared after I typed the Stop command.
[01:54:49] [Server thread/INFO] [net.minecraft.server.dedicated.DedicatedServer]: Stopping the server§r

[01:55:09] [Server Shutdown Thread/INFO] [net.minecraft.server.MinecraftServer]: Stopping server
Exactly what is says in the log file of the shutdown log.
[15:18:59] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 7177ms behind, skipping 143 tick(s)
[15:21:26] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 14240ms behind, skipping 284 tick(s)
[15:23:05] [Server thread/WARN] [net.minecraft.server.MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded? Running 11316ms behind, skipping 226 tick(s)
The Can't keep up I was talking about.
As for the Server startup I compressed that to a .zip file and uploaded it here due to that it is just too big to copy paste.
