How do I get back the time and date on the home screen of my Alcatel U5 3G?

Due to some app doing a clean up my phone no longer displays the time and date in the centre of the screen like it used to when I unlock it. Is there any way to get them both back? Any advice would be greatly appreciated. Thank you.

Welcome to Android Central! Are you talking about a clock widget? Long-press any empty part of the homescreen, tap Widgets, and look for the clock widget. Long-press it and drag it back to the homescreen.
