The following can be used to get the date:
function date_date() {
var date = new Date();
var year = date.getYear();
var month = date.getMonth() + 1; if(month.toString().length==1){var month =
'0'+month;}
var day = date.getDate(); if(day.toString().length==1){var day = '0'+day;}
var hour = date.getHours(); if(hour.toString().length==1){var hour = '0'+hour;}
var minu = date.getMinutes(); if(minu.toString().length==1){var minu = '0'+minu;}
var seco = date.getSeconds(); if(seco.toString().length==1){var seco = '0'+seco;}
var date = year+'·'+month+'·'+day+'·'+hour+'·'+minu+'·'+seco;
Logger.log(date);
}
