all the credit goes to zifis for his lockscreen.

changelog
now in both landscape and portrait mode
new font and just top rectangular bar and 12 hour time zone

just paste the landscape.png image in /opt/qtlockscreen/green_on_grey

and the font in /home/user/.fonts
and that's all .

now it is all up to you , you can edit it your way .
i know i know :P
it is not that accurate as zifis's portrait one but this is for the one's who wanted to use landscape mode .
