Workflow

Copy folder with pictures to working directory (e.g. My Documetns\My Pictures\ToFile\)
Find difference between camera time and real time
Correct both EXIF times in JPG files and file times for all other files. (Exifer or Exiftool)
Rotate images (Exifer)
Remove Unwanted pictures
Rename files based on creation date + sequence number (e.g. 2008-01-01-0001.jpg)
Tag images and move to folders (EXIFER)
Move to archive directory on YM (Y:\Picutres)

Add 2 minutes 30 seconds: exiftool -r -Alldates+=0:2:30 .

touch -r somefile.avi -d "-1 hour +3 minutes -5 second" somefile.avi

exiftool -r "-FileName<DateTimeOriginal" -d %Y%m%d_%H%M%S%%-c.%%e .

for fn in *.avi ; do nn=$(stat --printf=%y $fn | sed -e 's/\..*//' -e 's/ /_/
' -e 's/[-:]//g') ; echo mv $fn $nn.avi ; done

Exifer is a discontinued product but quite good. I am still evaluating other tools as recommended on his site as well as others.
Cygwin is a source for bash, touch, and stat commands.
Exiftool is a command line tool written in Perl but with command line versions. Any version should work but the one used writing these notes is this one.

 ==How to change the EXIF dates in a file==
+===Using exiftool===
 <pre>
 Add 2 minutes 30 seconds: exiftool -r -Alldates+=0:2:30 .
 </pre>
+===Using Exifer===
+*Select files to change
+*Choose menu item EXIF/IPTC:Edit... (Ctrl-E)
+*Choose EXIF Data Tab
+*Choose Date Tab
+*Choose +/- Day and hour offset. Midnight represents no change to time.
+**Examples:
+**Camera is 10 minutes slow.<br/>Add 10 minutes choose "'''+'''" and "12:'''10''':00 AM"
+**Camera is 10 minutes shy of 2 days fast, i.e. 1 day 23:50:00 fast<br/>then either subtract 2 days from all pictures followed by adding 10 minutes or use "'''- 1''' day 11:50:00 '''PM'''" as the offset.
