create timestamp

[JOHN FARRUGIA]

I am trying to create a statement which will populate a timestamp cell. I need to take the current date, add a day then add a specific time. I have tried the following statment but have had no luck. Any suggestions?

update tags.triggers set next_time_of_day=str_to_date(adddate(current_date(),1) 11:12:12 %Y-%m-%d %H:%i:%s) where id=1;
