Tweak to add seconds to the status bar clock

Hi,
I read in the last few days of a tweak which adds display of seconds to the clock in the status bar, which normally just displays hours and minutes. I'm now ready to install it but cant find where I read about it. Please can anyone advise? Thanks.

 

You should be ok. If the tweak is not compatable you will go into safe mode and then you can go back to cydia and remove said package.

 

That's the one... great, thanks Marilyn.
