Parse the IFTTT date to dd-mm-yyyy hh:mm:00

IFTTT_DATE.js

function IFTTT_DATE(str){
  var time = str.split(" "), months, timestring, parsed_hour,
      year, month, day, hour, minute, output;
  
  months = {
    "Jan": "01", "January": "01",
    "Feb": "02", "February": "02",
    "Mar": "03", "March": "03",
    "Apr": "04", "April": "04",
    "May": "05", 
    "Jun": "06", "June": "06",
    "Jul": "07", "July": "07",
    "Aug": "08", "August": "08",
    "Sep": "09", "Sept": "09", "September": "09",
    "Oct": "10", "October": "10",
    "Nov": "11", "November": "11",
    "Dec": "12", "December": "12"
  };
  
  year  = time[2];
  month = months[time[0]];
  day   = time[1].replace(",","");
  
  timestring  = time[4].split(":");
  parsed_hour = (+timestring[0]).toFixed(0);
  
  if (time[4].indexOf("PM") > -1 && parsed_hour < 12) {
    hour = +parsed_hour + 12;
  } else {
    hour = parsed_hour;
    
    if(hour <= 9) {
      hour = "0" + hour;
    }
  }
  
  minute = timestring[1].substring(0, timestring[1].length - 2);
  output = day + "-" + month + "-" + year + " " + hour + ":" + minute + ":00";
  
  return output;
}

Does this work in Google Scripts for SpreadSheet?

@oscarmorrison a bit late, but this works.
