I can't set my clock right

[cleanair]

It's set at January 1st, 2015.
This happened after I abruptly lifted the computer off where it was sitting at and it turned black, so I restarted the computer.

Even if I use "use current location" it says "can't find current location."

Google, Quora, and Twitter, Yahoo doesn't work, saying that my time is set far too back.
I thought this site wouldn't work but it does.

Do you mean that you can not change your clock time?

Go to system preferences, then Time & Date. Unlock the pane (click the padlock in the lower left corner)
Uncheck "Set Date & Time Automatically"
Now you can change the time and date manually to the correct settings.

Then -
Shut your Mac off (from the Apple menu)
When it finishing shutting off, turn it back on normally.
That may get everything working properly.
Recheck "Set Date & Time Automatically".
Finally, make sure the your startup disk is set to your boot drive (unlock your Startup Disk pane if you need to change the setting)

The computer turned black again, and again when I turned it back again the time was reset to 2015. I think it might be something to do with plugging in the power cord. I think both times it happened right when I plugged in the power cord. The power cord is a bit on the broken side too, since it's not charging right now. It has tear on the side where it connects to the computer (the wire is showing for the first 10 cm from the rubber cover ripped out).

Can you tell us which MacBook Pro you have?
Go to your Apple menu, then About this Mac. That will show exactly which model you have.

Is the battery good? (Does it hold a charge, and run on battery if you disconnect the power cord?)
Do the contacts in the power cord connector look OK (both the cord, and built-in connector)
If you don't get charging on the battery, that can be a bad power adapter or cord, or the internal connector (the magsafe board or DC-in board - either name is OK), or the battery simply needs to be replaced.
Easiest next step is to try a different power adapter. Maybe you have a friend with a MBPro, or you could try a quick test at an Apple store. You will see within a few seconds if the battery will charge with a different (good) power adapter.

Yes the battery is good.

So what happens is:
1. Every time I disconnect the power cord, computer resets (goes black and when I turn it on the date is always January 1st, 2015)
2. Then when I connect the power cord, it doesn't charge.
3. When I disconnect and reconnect the part of the cord where it connects with the outlet, it begins to charge again.
4. But when I disconnect or the part of the cord where it connects to the laptop moves a bit, back to number 1.

You need to replace your power adapter, as your next step.
