SOLUTION: JS Script for renaming images after date taken (CreateDate) and normalizing date to UTC+0

Hi, I hope the following helps. :)

The script takes the "CreateDate" from exif, looks up a give time offset and normalize it to UTC+0. I recognized that .mov from a Google Photos export was UTC+0 and .heic was UTC+2. This offset made my renaming obsolete. Thats why I developed this script to normalize the dates.

var fileName = item.name;
var createDate = item.exifToolValue("CreateDate");
var offsetTime = item.exifToolValue("OffsetTime");
// var fileName = "IMG_0362.HEIC";
// var createDate = "2022:05:20 17:39:09";
// var offsetTime = "+02:00"

// ISO date: 2009-06-30T18:30:00+02:00

if(!createDate){
return fileName
}

var createDateDate = createDate.split(' ')[0].replace(/:/gm, '-');
var createDateTime = createDate.split(' ')[1];

if(!offsetTime){
offsetTime = "+00:00"
}

// returns 2022-05-22T17:39:09+02:00
var myNewDateString = createDateDate + "T" + createDateTime + offsetTime;

// returns 2022-05-22T15:39:09.000Z (normalized to UTC+0)
var myNormalizedDate = new Date(myNewDateString).toISOString();

// returns 2022-05-22T15:39:09
var finalDateString = myNormalizedDate.split('.')[0].replace(/:/gm, '-')

return finalDateString + ".0Z_" + fileName
