Where is time stamp coming from?

ezucker posted this 3 weeks ago

The time stamp on my RAW image files are sometimes off an hour because of a change in time zone. I correct this in Lightroom before exporting the JPG photos which I then import into Time-Lapse Tool. But Time-Lapse Tool displays the original incorrect time. I cannot figure out what file attribute Time-Lapse Tool is getting this time from.

I am using Attribute Magic Pro software to examine every time stamp attribute in the JPG file, but none of them show the time displayed in Time-Lapse Tool. I'd be happy to send you a sample JPG file, if that would be helpful.

The software tries EXIF timestamps in the following order: - DateTimeOriginal (0x9003) - DateTimeDigitized (0x9004) - DateTime (0x132)

If none of these tags found, it takes modification time (LastWriteTime) from the image file.

If filesystem does not support modification time the Tool takes file creation time.

Hope this helps.

That does not appear to be happening in this case. The DateTimeOriginal says: Date/Time Original : 2025:03:04 23:04:33-08:00

But when this image is imported into Time-Lapse Tool, the Frame Info time stamp says 12:04 AM.

Ok, we checked the examples you sent.

The Tool takes dates from EXIF IFD group of tags, these tags do not include timezone information. At least in your case. The tags from "composite" group is not taken into account yet.

The only suggestion is to temporarily adjust PC timezone to match the timezone of photos.

Thank you for looking into this.

What does IFD mean?

EXIF Image File Directories. Not copy-pasted name fully, sorry.
