I follow the same instructions as

1) create AmberClock.sh and
2) Paste this in it
(#!/bin/sh
#call AmberClock.sh color font size
sed -i "/LockScreen MLabelStyle#LockScreenLowPowerModeClockLabel {/,/color/c\\
LockScreen MLabelStyle#LockScreenLowPowerModeClockLabel {\\
font: \$FONT_FAMILY_"$2" "$3"mm;\\
color: #"$1"; " /usr/share/themes/base/meegotouch/libsysuid-screenlock-nokia/style/libsysuid-screenlock-nokia.css
sleep 1 && /sbin/initctl stop xsession/sysuid && sleep 1 && /sbin/initctl start xsession/sysuid)

3) save AmberClock.sh to /home/user/MyDocs/.AmberClock as


4) using custom action

in active to run paste
sh -c "echo rootme | devel-su -c '/home/user/MyDocs/.AmberClock/AmberClock.sh 980016 BOLD 13'"

When deactive to run paste
sh -c "echo rootme | devel-su -c '/home/user/MyDocs/.AmberClock/AmberClock.sh FFFFFF LIGHT 10'"

and testing but nothing change using correct time criteria and my default root password is "rootme"
