high please use code above to follow my flows.
I create timestamps in node-red using the moment node.
I insert these into a TABLE called data using the correct mySQL TIMESTAMP format/syntax and all is well. Although when I query it back from the database is returns the columns in msg.payload array, as it should, but the timestamp in the array is a different time value to what I put in.
in the pink box i use [SELECT * FROM data] to query the data table for all columns. I have circle in pink the timestamp that I am uncertain of where it comes from because in mySQL table it is not stored in this way. refer to next image.
circled in blue is the exact way it is stored in mySQL TIMESTAMP column
where is the TIMESTAMP: "2020-03-17T07:35:38.000Z"
coming from?
