I have some old scanned images with Original dates early in the last century. I am trying to set the file system date to be the same as the original image date.
$ exiftool '-filemodifydate<DateTimeOriginal' -overwrite_original *.jpg
This works for back to 1965, but not earlier.
$ exiftool -args 1915\(aprx\)aaltjebosma.jpg | grep Original
-DateTimeOriginal=1915:05:05 11:40:00
$ ls -lt 1915\(aprx\)aaltjebosma.jpg
-rw-r--r-- 1 asp asp 918170 May 5 2015 1915(aprx)aaltjebosma.jpg
As you can see, the filedate got set to the year 2015 instead of 1915 in this case.
I can manually set the filedate to 1915 using the touch command:
$ touch -t 191505051140 1915\(aprox\)janpater.jpg
$ ls -lt 1915\(aprox\)janpater.jpg
-rw-r--r-- 1 asp asp 978527 Apr 5 1915 1915(aprox)janpater.jpg
Is there some way to get exiftool to write the earlier filedate?

Interesting. This is very system dependent. On many systems you would be limited to 1970 or later.

Cool.
Unfortunately I rely on standard library date/time routines for this. These libraries have certain limitations. I have checked, and the behaviour is the same for me on OS X when I try to set a year to 1915. The problem is the Time::Local::timelocal() function. I can't see any work-around short of re-writing the standard library routines (which I may do some day because these limitations bug me).

Did I forgot to mention that I am running on Ubuntu 14.04?
At the moment, I have only ~30 pre 1965 files. For the time being, I'll just "touch -t" them. Does that work on OS X as well?
Yes, the touch worked on OS X.
