 Description   
Resolution

This report is invalid as this bug seems to be caused by Java.
See Galaxy_2Alex's comment:

That would be most likely a Java issue

At random times, the game will speed up by a lot and after a few seconds will return to normal.
Has not happened in a superflat world. There seems to be no "real" way to reproduce this, but it does happen and has happened before in the snapshot.

Play a world for long enough. You will get it eventually.

When you wake your computer from standby, to Minecraft it appears that the time suddenly changed, and it thinks that it lagged and needs to catch up, so it runs as quickly as possible until it catches up to where it thinks it needs to be.

Confirmed for

  • 1.8.3 massive tick speed up when leaving Mincraft (with open inventory) running and the pc goes into standby and then closing the inventory again

I am not sure if this relates to this, but I got:

[20:01:44] [Client thread/INFO]: [CHAT] [Feuerwerksrakete] * 1 an Marcono1234 gegeben

(This can also be triggered when using a too high /gamerule randomTickSpeed and then setting it back to the default one)

No answer, assuming no longer an issue.

Comment by Talven81 [ 26/Nov/13 ]

Is this still a concern in the current Minecraft version 1.7.2 / Launcher version 1.3.4 ? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

I don't know what's SOP but simply copied all the stuff over here...

Comment by David Harmon [ 13/Aug/13 ]

@Kumasasa: Thanks for reopening the bug. Is it SOP for a Wiki report to copy the entire report from there? I thought I'd decently summarized it, but I can see why you might want a straight copy.

Timelapse bug?

The other day I took the latest update, . It contained several bugs, which I'm not going to bore you with, but one, though, since it is of interest to this article. You see, I had played until my computer entered standby mode. Then, when I reopened it a few hours later, I looked to the sky, and the Sun moved with tremendious haste! And that wasn't it, the cows in my farm ran like they had inhaled kilograms of concentrated heroine. Then, I dived into the water, and drowned before I could blink! Cooking wood was speeded, everything. Except for myself. I was still the same, unhyped Player. Is this a bug?

  • That happens when you forget to pause the game. Minecraft5025 19:30, 22 August 2012 (UTC)
    • Same thing can also occur on servers while running. It has happened during the twelfth season of Minecraft Ultra Hardcore. See: http://www.youtube.com/watch?v=trCSukJNLag (Skip to around 8:45, this is where the players start finding out something is wrong.) A server reset later fixed the issue, but the occurrence seems random. --UltimateBacon 10:54, 31 July 2013 (UTC)
      • Heh – that happened to me once last month... fortunately I was at my farm, so I was just mystified rather than slaughtered. You can still see my confused comment over at Talk:Chicken. Also, this has been reported as MC-6330. --Mental Mouse 01:48, 13 August 2013 (UTC)
Comment by David Harmon [ 13/Aug/13 ]

No, this is current – it happened to me last month (ETA: 1.6.2), and it's been recently reported by another Wiki user at http://www.minecraftwiki.net/wiki/Talk:Day-night_cycle#Timelapse_bug.3F .

It was also encountered by the Ultra Hardcore crew: http://www.youtube.com/watch?v=trCSukJNLag . Skip to around 8:45, which is when they first see speedy monsters – it takes them a while to realize the sun is speeded up too. They fixed it with a server restart.

This does not seem to happen anymore. I'm willing to say that it should be closed.

Comment by FireHunterX [ 01/Feb/13 ]

I got:

Time ran backwards! Did the system time change?

About 5 minutes after the speeding up ended.

Comment by FireHunterX [ 22/Jan/13 ]

Right.
I assume the same result will occur if I use Minecraft.app instead of .exe?
I use a Mac.

Comment by Kumasasa [ 19/Jan/13 ]

Start the game with

java -Xmx1g -Xms512M -cp Minecraft.exe net.minecraft.LauncherFrame 

and look if the console reports something like

Cannot catch up, did the system time change ?

Comment by Alexander Hammett [ 19/Jan/13 ]

The game catches up when you put it to sleep over night?! I just had it happen to me. Never happened before...

Comment by FireHunterX [ 07/Jan/13 ]

Not to be confused with some computers that go to sleep causing this upon wake.

That is the game catching up.
This is when it just happens for no reason, as if you are in a lagspike and the game is catching up.

Comment by FireHunterX [ 07/Jan/13 ]

Please bear in mind that it says "Is modded: Very likely, Jar signature invalidated".
...Because I replaced char.png with a copy of my skin so that it shows offline.
Also note that it says "Suspicious classes: No suspicious classes found."

Please force a crash by pressing F3 + C for 10 seconds while ingame and attach the crash report here.
