For me it worked to add the phrase  explicit defaults for timestamp   ON  without quotes into the config file my ini    Make sure you add this phrase right underneath the  mysqld  statement in the config file    You will find my ini under C  ProgramData MySQL MySQL Server 5 7 if you had conducted the default installation of MySQL

First you don t need to change anything yet      Those nonstandard behaviors remain the default for TIMESTAMP but as of   MySQL 5 6 6 are deprecated and this warning appears at startup   Now if you want to move to new behaviors you have to add this line in your my cnf in the  mysqld  section   explicit defaults for timestamp   1   The location of my cnf  or other config files  vary from one system to another  If you can t find it refer to https   dev mysql com doc refman 5 7 en option-files html
