Widget Logic, specific days and times

Hi there,

I am using th widget “Widget logic” and had a read through this http://wordpress.org/support/topic/how-to-hide-and-display-specific-widget-at-certain-time-timetable?replies=5 (which works).

As I do not have a clue about tags/programming, how do I set a widget to only appear on Sundays between 12 and 14 hours?

Many thank
Christian
