I have stored the "dates" (it is a varchar) and I need to take it to another format to do operations, and many poor options and the one that seemed to help me dateformat arrogates values to me in zeros, I also have to keep the hours and minutes , the system is going to be in php, in another php I use dates the strtotime worked, I imagine that / I will have to replace them with "-"
attached images of the base, what I have to do is move from date to new date
