GLCD library version 3 (end of life - no longer supported)

Just bought a 128x64 display and downloaded the library. Excellent library and the documentation was extremely useful in connecting the display.

Just one query, I am trying to run the ClockFace sketch and am getting a number of error when I try to compile it for a Mega2560:

clockFace.cpp:13:82: error: Time.h: No such file or directory
clockFace.cpp: In function 'void setup()':
clockFace:31: error: 'setTime' was not declared in this scope
clockFace.cpp: In function 'void loop()':
clockFace:37: error: 'now' was not declared in this scope
clockFace:48: error: 'hour' was not declared in this scope
clockFace:48: error: 'minute' was not declared in this scope
clockFace:48: error: 'second' was not declared in this scope
clockFace.cpp: In function 'void checkSetButton(int, int)':
clockFace:66: error: 'adjustTime' was not declared in this scope
clockFace:71: error: 'hour' was not declared in this scope
clockFace:71: error: 'minute' was not declared in this scope
clockFace:71: error: 'second' was not declared in this scope

What am I doing wrong?

Cheers
