While Photos for macOS has amend well since its founding several years ago , it still has some “ third rail ” features that you need to be careful about touching because they could be painful to fix . The worst of these isImage > Adjust Date and Time .
When used carefully , it ’s a manner to fasten the incorrect day of the month and meter on a unmarried photo or to conform the offset for a mathematical group of photos . Say you had a television camera localise to the wrong meter zone , date , or fourth dimension of day — or all three . This was a frequent job with older cameras that would reset to an arbitrary time if their battery hunt out . But it ’s comfortable to do today : just move around a few metre zones or set the day of the month falsely without noticing it .
This offset expose itself in Photos when you pool images from dissimilar sources , like a photographic camera and your iPhone , and they ’re interleaved wrong . Or they ’re just in the wrong place : time of day , daytime , or years away from where you expect .
Adjust Date and Time lets you correct for this . Select a group of epitome and picture that are all ill-timed by the same amount , like 2 months , 5 hours , and 1 time zone . In the dialogue , enter the correct first date and time ; you could also change the time zona . Apple then set all the images and videos by that factor , and it define all the sensitive to a different time geographical zone if you selected one .
But what if you were to enter thewronginformation ? One reader sent their images about 2,000 year into the future , all 27,000 of them . Apple does n’t offer an undo — there ’s no way to chatter and reverse this operation .
The best solution is to change by reversal the stolon . The Adjust Date and Time feature does n’t set all selected spiritualist to a single date and clip , but rather adjusts all the image by the same level as the remainder between the original and familiarised time of the first simulacrum .
Imagine you had three images in a choice taken in 1990 on January 14 at 5:30 pm , January 15 at 10:30 am , and January 20 at 8:01 pm . countersink the adjusted escort and clock time of the first image to April 20 , 1983 , at 8:30 postmortem , and those images would now be stamp in 1983 at April 20 at 8:30 postmortem , April 21 at 1:30 phase modulation , and April 26 at 11:01 phase modulation . exchange them back would be a matter of selecting the same set and entering the original capture time : January 14 , 1990 , at 5:30 pm .
Here ’s how to reset the offset :
If after play along step 2 above , Photos wo n’t let you prefer Adjust Date and Time in stair 3 if you have anyreferencedmedia in the selection . If any are included , you have to desex or turf out them . Either create a raw bright record album that excludes them or import those referenced images and videos into your subroutine library .

If you do n’t bed the correct time for the look-alike in step 4 , watch over these steps :
Yes , it ’s ironical that you have to open up a unlike Apple app to get the information you ask .
If the above is too fussy for you , if you find that you have too many unlike set of offset range , or if there ’s worse weirdness going on that you think could be some form of correction , you may also turn to a reliever . However , if iCloud Photos is enabled , the fill-in can only form if the iCloud put inPhotos > Preferences > iCloudis set to download full - resolution look-alike as described in “ How to make a local backup of your iCloud Photos synced library . ” If iCloud Photos is set to optimized , there ’s no way to reverse .
