Have no idea what forum to post this in.

You've all heard of ways to change the meta and file embeds to different dates, times etc however ...

This knucklehead assisting me at a wedding had his camera date set to AM instead of PM.
I want to advance his 'date created' 12 hours but keep the times the same so when I drop the
whole bundle of our work into Adobe Bridge it'll all be chronologically seamless and in order.

HELP! Any ideas will be very very welcomed!
THis will surely save my hours of work.......

Check this app out.

(BTW-it was the first hit when Google searched on "batch date change mac")

[Headshot]

Thanks Porter, I think this is your full time job!
You've been the answer to so many of my issues over the months....

I just installed the trial and upon first glance this appears to be a renaming-only app,
I'm looking into seeing if I can only bump the existing time up 12 hours....

[Headshot]

Check that, I just saw the 2nd app in the download "Better FInder Atribute" etc....
I think this may work I'll keep you posted!

[Headshot]

Son of a Beehive it works. Just shelled the $15 for the license.
Thanks again, I'm just terrible when it comes to search word combo ideas....

You saved me a world of grief!

For future reference, I believe the following would work:

for i in *;do touch -m $i;done

[FireWire]

i think Automator should be able to do this also?

[Headshot]

It works, what can I say, perfectly.

Even consumer grade library management software (Picasa, iPhoto) can do bulk timestamp changes. I assume Lightroom and Aperture can do the same.

[ghporter]

Holy COW!! I never even looked at iPhoto. You highlight the files you want to edit, Ctl-click for context menu, select "Batch Change" and then choose "date" from the drop down... That's way easier than I had expected from iPhoto-probably because I stopped using iPhoto about four versions ago when everything seemed like it was intentionally difficult and complex.

[Headshot]

well, as a business, the $15 is worth the grief to end the problem with a solution I (we) found in 5 minutes so all's good.
I've never liked iPhoto or most of the iApps as it seems like we've spent so many years learning the nuances of complicated pro apps that the 'simple' nature of those seems so darn hard.

BTW can the iPhoto thing do the "add X-amount" of minutes, sec's years etc and subtract? Because the great thing about the one I just got (can't even remember the name) is just that, anything less would just mod them all to one time.

Ok great. What pro app are you using that lacks this feature?

Of course, both Picasa and iPhoto can do that. You set the correct time for one and it has the option of applying same delta to the rest. Setting them all to the same time would be rather useless.

That will change the last modified time, not the shot time in the EXIF, and that will change the modified time to now. How useless.

Ahhh.. I forgot about the EXIF metadata. My mistake. You can specify a specific modified time with the touch command though.

[Spheric Harlot]

He wants to add twelve hours to whatever the time is, and he's not interested in "last modified" AT ALL.

Well, there is only accessed and modified timestamps at the filesystem level, I believe, and like I said, I forgot about the EXIF metadata...

[Spheric Harlot]

Can you change "date created" using the Terminal?

If not, it's useless for most media management.

Unless HFS+ supports some sort of extended attribute, perhaps via that thing added to a recent version of OS X (can't remember it's name, UTI, I think?!) or old school dual fork stuff, at the BSD/shell level there only exists access and modified dates at the file system level, I believe...

[Headshot]

i needed a quick answer, got it within a few minutes of the original post and carried on with my day, I'm happy.

You can do it using SetFile. Unfortunately, it's only present on your system if you have the developer tools installed.
