Yes there are. The meta info format is called EXIF, and there is a command line tool called exiftool which can to exactly that.
Example invocations from the man page:
exiftool -DateTimeOriginal-=’0:0:0 1:30:0’ dir
Adjust original date/time of all images in directory "dir" by
subtracting one hour and 30 minutes. (This is equivalent to
"-DateTimeOriginal-=1.5". See Image::ExifTool::Shift.pl for
exiftool -createdate+=3 -modifydate+=3 a.jpg b.jpg
Add 3 hours to the CreateDate and ModifyDate timestamps of two images.
exiftool -AllDates+=1:30 -if ’$make eq "Canon"’ dir
Shift the values of DateTimeOriginal, CreateDate and ModifyDate
forward by 1 hour and 30 minutes for all Canon images in a directory.
(The AllDates tag is provided as a shortcut for these
three tags, allowing them to be accessed via a single tag.)
I am sure you can set the year to exactly 2010 in some way.
