Update timestamp from Version to Master

Hi. I just realized that I never changed my primary camera's time stamp to DST in November. Every Image recorded by that camera is off by 1 hour. (This is not helpful when you are trying to organize Images by solar time.)

To fix this, I selected all Images taken by that camera since the start of DST (11/6/11), and using "Metadata→Adjust Date and Time" I rolled the time back one hour, and checked "Also change Master files". Four hours later, the operation was done ... with a long list of files that were not changed because they were off-line. (This list was in a small dialog box. I could do nothing with the list.)

So I added the additional filter "Off-line", and created an album of the 874 Images that had their time corrected, but not their Masters.

Is there any way, once these Masters are on-line, to correct the time of the Masters?

I considered using "Write IPTC metadata to Masters", but the time is (afaik) in the EXIF and not in the IPTC data set.

I suppose I could push the time back one more hour for all of these, including their Masters, and then pull it forward one hour, not including their Masters, but that is prone to user error -- and this user is _especially_ prone to binary reversals (were we to travel together by car, you would want me to navigate while you steered 😉 ).

Thanks in advance.

Hello Kirby,

I suppose I could push the time back one more hour for all of these, including their Masters, and then pull it forward one hour, not including their Masters,

That is what I have been doing, to correct the master files, after "apply to master file" was possible again.

But I think you can do it less complicated - it should suffice to adjust the time of the versions by one second - with "Apply to masters" enabled. The masters will be tagged with exactly the same time as the versions, not incrementally adjusted to their old time -afaik.

You may change the second back, if your clocks are very exact, but I usually do not bother to do that ...

Cheers

You are welcome!

How is the "sorting by solar time" coming along?

That was today's plan, since ********.

Woke up this morning with house chores to do, hence some free processor cycles. Was going to let loose your workflow on my Library, but discovered that the time stamp was wrong on 4,587 Images, and so set about correcting that first.

Tonight is still a possibility, though. Have some pictures I must ready for tomorrow, first.

And then: Lion!

😀 Kirby.

I presume "belated" would have scurried, crab-wise, past the censors.

Kirby, just a caution - I noticed that it is nearly impossible to do date calculation in AppleScript that works well independently of the Date&Time localization settings - so just in case you should get weird results while using my script (like day and month switched), don't waste your precious time with debugging but contact me asap, safe your time for "polished apples" or for fun with Lion - I just had to deal again with broken date localizations in this thread Re: Easter 2011 is missing on the Holiday subscription.

Cheers

I have not attempted adjusting times and dates.

But I'm assuming you have this problem because you can't change the Master without changing the Version?

Thanks. Have not gotten that far. Something went wrong with the time-of-capture update. Many hours of processing, a Force Quit, and now a few hours into a repair. Afaict, something was causing Aperture to reprocess every Master (at about 4s/Master), and then something (perhaps by my hand) caused this to stop advancing while still processing (I could access the Aperture menus, but couldn't quit).

😟

At least the repair appears to be going smoothly.

Yes. But the lesson to take from it is to have all needed Masters on-line prior to writing changes to the Masters.

O.K., but even such an user error should not result in Aperture hanging and corrupting your library - this looks like a bug to me.

I agree. Imho, either the off-line Masters should be marked for later update, or the user should be informed prior to the update (and given an option to cancel) that there are Images with off-line Masters and that these will not be updated.

I will file a report.
