WorldClock_NeoMatrix8x8 -what does this mean!

Arduino: 1.6.4 (Windows 8.1), Board: "Pro Trinket 5V/16MHz (USB)"

WordClock_NeoMatrix8x8.ino: In function 'void setup()':
WordClock_NeoMatrix8x8:157: error: 'class DateTime' has no member named 'unixtime'
WordClock_NeoMatrix8x8:162: error: 'class DateTime' has no member named 'unixtime'
Moon.ino: In function 'void mode_moon()':
Moon:85: error: 'class DateTime' has no member named 'unixtime'
calculateTime.ino: In function 'DateTime calculateTime()':
calculateTime:24: error: 'class DateTime' has no member named 'unixtime'
calculateTime.ino: In function 'boolean checkDst()':
calculateTime:49: error: 'class DateTime' has no member named 'dayOfTheWeek'
'class DateTime' has no member named 'unixtime'

Can someone help me understand this string of code and where i need to fix it please, its a school project and I'm really stuck.

What library are you using? Link to it preferred. Are you using the example from that library?

here's the error message

im a noob when it comes to programming on arduino need some help!

here the links to the lib i used:

WordClock_NeoMatrix8x8.ino (6.04 KB)

    theTime = theTime.clock() + 150;

WordClock_NeoMatrix8x8:157: error: 'class DateTime' has no member named 'clock'

So, why do YOU assume that you can call a method that doesn't exist?

Why are you trying to assign a number to an instance of the DateTime class?

the libraries i used for this project.

i'm not able to program it please can you get back to me because i need to submit it for my school finals.
i've been trying for months to get this to work.

i have linked the .ino file for more reference.

help me please. get back to me asap.
