The module contains two functions:

   Get-ExifDateTaken -Path <filepaths>

       Takes a file (fileinfo or string) or an array of these
       Gets the ExifDT value (EXIF Property 36867)

   Update-ExifDateTaken -Path <filepaths> -Offset <TimeSpan>

       Takes a file (fileinfo or string) or an array of these
       Modifies the ExifDT value (EXIF Property 36867) as specified


# Example: Rename files based on DateTaken value

gci *.jpg |
Get-ExifDateTaken |
Rename-Item -NewName {"Holiday Snap {0:MM-dd HH.mm.ss dddd} ({1}).jpg" -f $_.ExifDateTaken, (Split-Path (Split-Path $_) -Leaf)}

# Example: Correct DateTake value on a set of .jpg images by specifying a time offset

gci *.jpg|Update-ExifDateTaken -Offset '-0:07:10' -PassThru|ft Path, ExifDateTaken

# Example: Update DateTaken & Rename files based on Date

gci *.jpg |
Update-ExifDateTaken -Offset '-0:07:10' -PassThru |
Rename-Item -NewName {"Holiday Snap {0:MM-dd HH.mm.ss dddd} ({1}).jpg" -f $_.ExifDateTaken, (Split-Path (Split-Path $_) -Leaf)}

Script Help, Update-ExifDateTaken
---------------------------------

<#
.Synopsis
  Changes the DateTaken EXIF property in an image file.
.Description
  This cmdlet updates the EXIF DateTaken property in an image by adding an offset to the
  existing DateTaken value.  The offset (which must be able to be interpreted as a [TimeSpan] type)
  can be positive or negative - moving the DateTaken value to a later or earlier time, respectively.
  This can be useful (for example) to correct times where the camera clock was wrong for some reason -
  perhaps because of timezones; or to synchronise photo times from different cameras.
.Parameter Path
  The image file or files to process.
.Parameter Offset
  The time offset by which the EXIF DateTaken value should be adjusted.
  Offset can be positive or negative and must be convertible to a [TimeSpan] type.
.Parameter PassThru
  Switch parameter, if specified the paths of the image files processed are written to the pipeline.
  The PathInfo objects are additionally decorated with the Old and New EXIF DateTaken values.
.Example
  Update-ExifDateTaken img3.jpg -Offset 0:10:0  -WhatIf
  Update the img3.jpg file, adding 10 minutes to the DateTaken property
.Example
  Update-ExifDateTaken *3.jpg -Offset -0:01:30 -Passthru|ft path, exifdatetaken
  Subtract 1 Minute 30 Seconds from the DateTaken value on all matching files in the current folder
.Example
  gci *.jpeg,*.jpg|Update-ExifDateTaken -Offset 0:05:00
  Update multiple files from the pipeline
.Example
  gci *.jpg|Update-ExifDateTaken -Offset 0:5:0 -PassThru|Rename-Item -NewName {"Holday Snap {0:MM-dd HH.mm.ss}.jpg" -f $_.ExifDateTaken}
  Updates the EXIF DateTaken on multiple files and renames the files based on the new time
.Outputs
  If -PassThru is specified, the scripcmdlet outputs FileInfo objects with additional ExifDateTaken
  and ExifOriginalDateTaken properties that can be used for later processing.
.Notes
  This scriptcmdlet will overwrite files without warning - take backups first...
.Functionality
  Modifies the EXIF DateTaken image property on a specified image file.
