LockSecondsIndicator is a tweak that will enable seconds on your Lockscreen. These will appear right next to your analog clock nice and tidy. There is also a feature within this tweak that will enable the dots that separate the hour, minute, and seconds to blink every second. Apart from the blinking dots, this tweak can be really useful and give you a better sense of time. You can find LockSecondsIndicator under the Big Boss Repo for FREE in the Cydia Store.
