Want to add red in less than 10 minutes

[Sxbbb]

If the time is less than 10 minutes, you want it to be green.

Now I tried the code : if(Time#([Over Time Machine],'hh:mm:ss') < Time#('00:10:00','hh:mm:ss') ,rgb(50,205,50))

but the result is like this which is still not correct

if( subfield(Time#([Over Time Machine],'hh:mm:ss'),':',2)<10  and subfield(Time#([Over Time Machine],'hh:mm:ss'),':',1)<1,

red(),

if( subfield(Time#([Over Time Machine],'hh:mm:ss'),':',2)>=11  and  subfield(Time#([Over Time Machine],'hh:mm:ss'),':',2)<=20 and subfield(Time#([Over Time Machine],'hh:mm:ss'),':',1)<1, Yellow(),

rgb(50,205,50)))
