Estou bastante confuso porque nemo está relatando que alguns arquivos não têm data definida. O que significa que não posso ordenar meus arquivos por data. Isso só está acontecendo com meus vídeos GoPro que vou adicionar. Mas ao verificar posso ver que Media Create Dateé realmente o momento correto da gravação.
Como faço para que a data correta seja mostrada no nemo e no bash ao classificar arquivos para meus scripts:

Timestamp FS vs EXIF
Seu gerenciador de arquivos usa carimbos de data/hora FS. (Armazenado separadamente dos dados do arquivo)
Enquanto os metadados exif fazem parte dos dados do arquivo.
exif info
Carregar metadados exif (datas, etc) para cada arquivo é muito mais lento do que apenas usar o FS Timestamp.
Opções de configuração ou plugins podem permitir que você adicione funcionalidades exif como classificação/informações de dicas de ferramentas/etc.
Diferenças de FS
Nem todos os sistemas de arquivos usam carimbos de data/hora da mesma maneira. Alguns não suportam os mesmos carimbos ou estão configurados para não usar todos eles.
Somente os timestamps suportados podem ser copiados para qualquer sistema de arquivos de destino e somente se eles realmente existirem.
Certifique-se de que sua câmera grava
modified/ marcações de data eaccessedhora, não apenascreatedAo instalar um sistema operacional ou configurar um armazenamento externo, certifique-se de usar um formato FS compatível com os recursos necessários. (Como, por exemplo, carimbos de data/hora).
Certifique-se de que as opções de montagem não estejam configuradas para ignorar timestamps ou outros recursos que você precisa.
