How to reproduce?

If i pick an Image an extract Exif Data The "Exif DateTimeOriginal" doesn't always match the AssetEntity. createDateTime or the AssetEntity.modifiedDateTime.
I want to sort my Image by DatetimeRange with the "createTimeCond" Filteroption. Sadly the Dates doesn't really match the Gallery Dates.

Logs

No response

Example code (optional)

File? result = await galleryImage.asset.originFile;
      var xdata = await readExifFromFile(result!);```

Unfortunately, these two times are not decided by me, but by the system API. I just pass the values.

@CaiJingLong
That's disappointing :/ I developed a diary app and it would be great to filter the image gallery by date. However, at least on my Pixel 7, the creation date filter doesn't align with my gallery (and the actual datetimes) at all. Nonetheless, it's still an awesome plugin!

@HenrikH96 Might be a timezone issue. At least this is the most obvious deviation between the AssetEntity.createDateTime and the assets meta data in e.g. Google Foto. Possibily depending on the timezone in which the asset was created and the timezone of device and or emulator you use.

[HenrikH96]

@mgudev7a I don't think it's a timezone issue. The discrepancy is in years, not hours. I have two separate issues:

1. createTimeCond does not work properly on my Android phone (Pixel):

   • I have several images from before 2022, but if I filter from 1900-2022, I don't get any results.
   • I worked around this by using updateTimeCond, but this introduces other issues.

2. AssetEntity.createDateTime doesn't match the creation date of the file:

   • Neither the EXIF data nor the data shown in my Photos app match the creation date.
