Title: Change picture dates/times by a fixed amount
Post by: Tolga on August 31, 2004, 12:37:40 am

I want to adjust the time of a bunch of pictures (incorrect time on the camera). I want to subtract a fixed number of hours from each picture. Any suggestions on how to do that?

I have the same problem. I forgot to adjust the camera clock for the daylight saving time. I don't think there is any way to mass correct that in MC.

I could make a custom "Time adjust" field and put there a value -1. It would work as a memo field and perhaps the value could be used later if a tool for correcting times will be introduced.

Here is a command line tool for editing some EXIF tags in JPEG files: http://www.sentex.net/~mwandel/jhead/ (http://www.sentex.net/~mwandel/jhead/). Though, I have not tried it yet.

I requested this a while back and didn't get much interest.

For what it's worth, I'd still like it.

I found two utilities:

Exifer
An editor for EXIF tags, "postcardware".

EXIF worked fine for me, thanks. For others who want to do a similar thing: After I use EXIF to change the date field, and reimport to MC, MC does not update the date because it has added a MC specific date field on the files. The solution is to delete all date values (just assign empy value to date), and reimport. Needless to say, backup before you do that!
