How to insert moment JS time into MySQL

This result happens because you are using the toISOString() method and it is not a valid format to insert into your DATETIME column. The correct format probably is YYYY-MM-DD HH:MM:SS(I think it depends on MySQL configuration, but this is the default) as the docs points out.

So you should try using moment’s format() method like this:

myDate =  moment(data.myTime.format('YYYY/MM/DD HH:mm:ss')).format("YYYY-MM-DD HH:mm:ss");

In fact, I don’t know what data.myTime is, but if its a moment object too, you can change the first format() method and remove the second one.
