This plugin adds a note based on time to YOOtheme Pro.

Do you need to add something on your page from the beginning of a time based date that should automatically be overwritten by newer content if its time has come? This element shows it including a placeholder for a special word like "yesterday".

Think of a daily quiz which result should be shown after 6 pm on the same day but visitors should also see the result while the new quiz is being published. Simply write "We have searched 'this' {yesterday}". On the present day visitors will read "We have searched 'this'" on the next  day they'll read "We have searched 'this' yesterday".
