I'm launching a weather balloon with light sensing equipment run by an Arduino and I'm running out of time. I'm fairly new to Arduino and need to get a project done for school. I'm using a simple photo resistor to gauge the light. I can't figure out how to install Real Time Clock (Arduino Playground - HomePage) and this Data Logging script (Data-Logger/Datalogger.ino at master · Make-Magazine/Data-Logger · GitHub) for an LDR. If I try to install the data logging script I get this error: http://i.imgur.com/MuxCx0D.jpg
Sorry if this is stupid, I just really need help.
Have you installed Time.h?
On the Arduino? I'm not sure how to do this
Adafruit has a good information here:
Yes, they're installed there. When I try to upload the Data Logging script it keeps talking about time.h
Did you restart your IDE after the installation?
This is what my directory looks like. 
As long as you are willing to learn, don't be sorry.
The IDE is the Arduino program you use to write and download your sketches.
Just close the Arduino program then start it up again.
Yes I have, It appears in sketchbook
Will you show us the path where you placed the Time library?

Don't have Apple, but it should be here:
EDIT: Wrong image attached new one
So it should be in the Arduino directory, or inside of "libraries"
If it is like Windows, it should only be in one location.
I can only rely on this link as I do not have a MacBook:
Okay so now that thats installed, if I upload the Data logger script, will it take time.h from the libraries folder?
When I try to verify my Data Logging script is still returns those errors 
Okay so now that thats installed, if I upload the Data logger script, will it take time.h from the libraries folder?
Look with Finder to make sure it is in one place. As stated earlier restart the IDE.
Maybe someone with a MacBook can chime in.
The IDE should list the path to your sketchbook folder (file -> preferences). In this folder you need another folder named libraries and you place your libraries in there. Still in their folders.
ie; on my machine (a Linux box) sketchbook is in my root folder so the path to the Time library looks like
~/sketchbook/libraries/Time/
The Time lib files are in that Time folder.
Generally to install a downloaded user lib you simply need to uncompress it into the /sketchbook/libraries folder. Then restart the IDE.
Ok, I got the neighbor's MacBook, install the Arduino software and the Time, TimeAlarms and DS1307RTC libraries with the method on the Adafruit WEB site then compiled the TimeSerial.INO that comes with the library and it worked fine.
I don't have the option to look at the Preferences as I do not have the menu bar "File Edit Sketch Tools Help", but I think it is a problem with the operating system on the MacBook. Is this true?
