I had a look at it, and the whole thing is rather confusing. Discussion text seems to be about SOURCE_DATE_EPOCH, but the only patch contained here does something else, i.e. changing how the datetime is stored on the FAT filesystem. Currently, mtools matches Windows' behavior: https://stackoverflow.com/questions/38549583/what-time-zone-does-a-fat32-sd-card-record-timestamps-in : "... The FAT file system records times on disk in local time. ..." Apparently some digital cameras do store time in UTC though. As far as SOURCE_DATE_EPOCH is concerned, this is apparently an integer (seconds since epoch), rather than a structured field showing hour/ minute/seconds, so timezone considerations should not really apply.
