This question already has an answer here:
I have 3000 photos taken this year (2017) on a camera which had the date & time set incorrectly so all these photos are stamped with a 2015 date.
I would like to change the time stamp on all of these photos. I am going to upload them to Google Photos eventually.
I know I can do this very easily on Google Photos but the problem is that there are other existing photos on the account and my 3000 photos will mix in with them so when I would want to change their date, I would have to go and hand-select one by one. And AFAIK there is no way to tell the Google Photo uploader to sync the photos into an album.
I guess an option would be to create the album on Google Photos via web and upload directly into the album but the upload will take forever and I am pretty sure I'd lose control over it (network issues, PC issues, etc).
So I thought I would do the change before uploading them. Is there any windows tool (command line will do) to - basically set the start date of the batch and the tool would move all the time stamps accordingly?
