Bug on uploaded photos


 

I'm not sure where I should post this but all the photos being uploaded to albums are showing years in the 1960s range instead of 2020.

Does this bug go here, Beta, or where?
?
Sincerely,
?

Margo -- I'm seeing all photos as having the taken date of 1969-12-3169, no matter when they were uploaded.

I don't know if this is a default for a photo that has no such metadata, or what. Definitely peculiar, as it's not even a valid date.

All bugs should be with a #bug hashtag.

The date 12/31/1969 is very suspicious to me, it is the day before the . Briefly, all UNIX machines and many others do not store dates internally as something like "12/31/69" but rather as an integer representing the number of seconds since some arbitrary point in time.? The integer is then converted on demand into whatever format the user desires. For UNIX machines, that arbitrary date is midnight UTC on 1/1/1970, which is why I think that this date is particularly interesting, as if someone fed -1 to a date integer.

Best,

Every photo in every album in my groups (including some taken yesterday) have a "Taken" date of 12/31/1969. I just posted this on beta.

That's right before Unix epoch time (1/1/1970, 00:00:00), question is how much, is it just one second so that the pictures' timestamp is 0xffffffff, or is it 12/31/1969 23:00:00? If you download an image, does the image file's EXIF header show that timestamp?

Either way, this sounds like a bona fide bug.

Peter,

All of our album photos have the same Taken date of 12/31/1969 as yours. This has to be a bug to report to Support.

I'm an idiot.

Epoch being 01/01/1970 00:00:00 GMT0 converts into a wall clock time & date between 5 and 8 hours earlier on 12/31/1969 within the lower 48, depending where you are at.

And 90 minutes later, it seems to have been fixed.

Thanks,

I suspect the 'time before epoch' will equal your local offset from UTC.
Seen that happen in Unix systems for decades.
