Problem with tmElements_t, new

I am not sure why there is an issue with my code. I am new to arduino if somebody could help me that would be great. The error message I get when trying to run my code is
Arduino: 1.0.6 (Windows 7), Board: “Arduino Uno”
Clock:21: error: ‘tmElements_t’ does not name a type
Clock.ino: In function ‘void timeToBytes()’:
Clock:76: error: ‘RTC’ was not declared in this scope
Clock:76: error: ‘tm’ was not declared in this scope
Clock.ino: In function ‘void addTime(int, int)’:
Clock:221: error: ‘RTC’ was not declared in this scope
Clock:221: error: ‘tm’ was not declared in this scope
Clock.ino: In function ‘void printTime()’:

Clock:271: error: ‘tmYearToCalendar’ was not declared in this scope

Clock.ino (8.99 KB)

Clock:21: error: 'tmElements_t' does not name a type

So, why do YOU think it does?

When I compile your code, I get only one "error" message:

Binary sketch size: 8,886 bytes (of a 258,048 byte maximum)

This tells me that you have NOT installed the Time library correctly, while I (clearly) have.

Yep just realized it thank you
