Fixing camera date taken time for pictures with PowerShell

I found a great page that for fixing the times of pictures that were taken with a camera. My problem was that I had two cameras that took pictures at the same time and I wanted to throw the pictures in a time-sequenced single place. The cameras were 49  minutes apart, so I had to fix them.

Is a  3 part series that shows how someone else did the same thing. My simple steps were:

1. Download the ExifDateTime.ps1 script
2. Start a powershell window
3. Make sure you've run Set-ExecutionPolicy RemoteSigned and cleared the "remote" property to allow the script to be run with File > Properties
4. Run command 
1. import-module "./ExifDateTime.ps1"
2. gci IMG*.jpg | Update-ExifDateTaken -Offset '-0:49:00' -PassThru|ft Path, ExifDateTaken

This fixes the times of all the IMG*.jpg files in my directory.

Later, I found there are other solutions out there if you search for Exif Date Time. In particular, I found ExifTool that allows a similar command that changes the time offset for pictures.
