What different on Date / Date Modified / Date Create in Windows 11

Question

Hi,

I am confused by Windows Files Explorer.

What is "Date" n Windows Files Explorer?

You can see the pictures below.

These files were taken on August 17, 2022, at 4:18PM, 4:20PM, and 4:32PM.
When I open the Windows Files Explorer to view these files on the SD Card

It shows the correct time.

But when copying to an internal SSD, the tab "Date" changes the timestamp to 7 hours forward.

The Date Modified tab shows the same timestamp on the SD Card, and Date Created shows the timestamp of the time when I copied to the HDD. (I understand this.)

But the question is why the tab "Date" is showing 7 hours forward (11:17PM, 11:19PM, and 11:21PM). (files are copied at about 4:37PM

Does anyone have an idea on this?

Answer 1

You went to more trouble than necessary there. You could have just enabled the Date column on the original card. Anyhow, you proved my point that the Date property did NOT change when the files were copied from one storage device to anther. The value of Date remains consistent across all media. Yes, it differs from Data modified, but your original message was indicating that the process of copying the files changed the Date property. It didn't.

The screenshot of the Mac proves nothing. It shows the Date modified and Date created properties which match up perfectly with what you see in Windows for those two properties.

The Date modified and Date created properties are file properties that are stored in the file system (e.g. NTFS, Fat32, ExFAT, etc.). They are not stored directly in the file itself. Whereas the Date column in Windows shows whatever date property Windows can find in the file itself (i.e. EXIF data).

If you want to compare Windows to Mac, in this regard, you'll need to find a way, on the Mac, to display the Date value that is stored within the file itself (i.e. display the EXIF data). It should be the same as you see on Windows because neither Mac or Windows touch the EXIF data in the file.

The 7 hour difference is clearly connected with the 7 hour time zone difference of your UTC+7 time zone. Although you appear to have everything set correctly, the time the camera is writing to the video file is incorrect. This is not a Windows or Mac issue. It's either a camera issue or an MOV file format issue. I think if you search that issue for video files and Panasonic LUMIX you will get hits. It appears this issue is specific to video files (and maybe specific to the LUMIX). You should not see any issue with the date EXIF data on still photos. See, for example: https://www.dpreview.com/forums/thread/4322770

Although I did not see any mention of a firmware update fix, it can't hurt to check for a firmware update for your camera.

There are indications that this may be a MOV file issue and not a camera issue. See: https://www.google.com/search?q=MOV+files+incorrect+time+in+EXIF+data

Answer 2

I appreciate your reply.

Yes, I go further than I should. Date issues may not be a big issue. It just annoys me.

I read the article you linked to. (Many thanks; I tried searching but couldn't find anything similar.) You're fantastic.

It helps me understand what caused this problem, which is related to the MOV files and also the GMT and UTC problems.

Now that I understand where the seven hours came from, everything makes sense!

Thanks
