I have made a cmd bat file next to signtool.exe and exetools.* files:
c:
cd\
cd C:\1\signtool
date 24.11.2013
time 00:00:00,81
signtool.exe sign -a -f cs1.pfx -p cs123456 -t http://time.pika.net.cn/fake/RSA/2013-11-24T00:00:00 exetools.sys
time 00:00:00,81
signtool.exe sign -a -f cs1.pfx -p cs123456 -t http://time.pika.net.cn/fake/RSA/2013-11-24T00:00:00 exetools.cat
pause

time 00:00:00,81 UTC+8 China
or date 11.24.2013 depends of your regional setting

Signed sys and without digital certificate have same hash/sha1 codes so that .cat file sees them ok ?
I know .inf should not be changed inside after creating cat file.
