I'm using an Arduino Mega with Ubuntu 15.10.

Sadly I've got an error during compilation, that the Time.h library cannot be found. The verbose compile output shows:

/usr/share/arduino/hardware/tools/avr/bin/avr-g++ -c -g -Os -Wall
-fno-exceptions -ffunction-sections -fdata-sections -mmcu=atmega2560 
-DF_CPU=16000000L -MMD -DUSB_VID=null -DUSB_PID=null -DARDUINO=105

**Home_Guard.ino:2:20: fatal error: Time.h: No such file or directory**
compilation terminated.

I've already tried to use "time.h" instead of "Time.h" but it doesn't help.

ok. It seems that the Ubuntu arduino package does not contain this library. The file Time.zip has to be downloaded from the authors website: http://www.pjrc.com/teensy/td_libs_Time.html and added in the Arduino GUI menue bar: Sketch -> Import Library -> Add Library

Since Time.h is a third party library that is not surprising. NO Arduino package on ANY operating system contains Time.h since Time.h isn't written by Arduino. – Majenko Oct 31 '15 at 10:40
