Yes, if you are running Minecraft 1.3 and above, simply press the T or / key to open the console, type
/time set <TIME-OF-DAY>, and press enter.
<TIME-OF-DAY> is in ticks. This means the start of the day is 0, nightfall is 12000, and the end of the day is 24000.
Does this not work for you? Here is a possible fix (WINDOWS ONLY):
- Download NBTEdit
- Make sure Minecraft is CLOSED. Not just on the main menu. CLOSED.
- Now you need to get the path to your Minecraft level file, and chances are its location (AppData) is hidden. Do this:
- Press the windows key + R and the Run window should come up.
- Type in
- The Windows Explorer will open, and the folder
.minecraft should be near the top. Open it, and then open
- Copy the path in the address bar.
- Open up NBTEdit. In the menu bar, click
File, then click
Open. In the address bar, paste the path you copied.
- Now, browser to your level's folder. Inside of it, you should find
level.dat. Open it into NBTEdit.
- If your world has been run on a 1.3 client, it should say
Data: 21 entries. Expand that node, and at the very top, chances are it says
allowCommands: 0. If it is missing, you must play that world on a 1.3 client. If it says
allowCommands: 1, then commands should already work.
- Click on
allowCommands. Then click on the Pencil in the tool strip. For a value, enter in
1. Now, click
- That's it! The solution above should now work in your world.
If you know how to make the above solution work in other operating systems, feel free to edit it.
