I want to get the time zone related info on a file on a SD card formatted in ex-fat. The file was created by a non-apple device. ex-fat does allow storing a time zone with each file which denotes the time zone where the file was created. My first try was to use diropen with readdir to locate dirent info for the file but dirent struct does not have any time zone info. My second approach was to look at the file resource values. I couldn't find any time zone related file attribute probably because that feature is ex-fat specific. The context is a mobile app running on an iPad with access to external storage. Any guidance will be appreciated. Thanks.
