There was a problem hiding this comment.
Can you please handle the possibly different sizeof(time_t) explicitly? E.g.
uint32_t meta = (maybe truncate?) sbuff.st_mtime;
SPIFFS_fupdate_meta(&s_fs, dst, &meta);
And similar in unpackFile below.
and the SPIFFS image file, take into account that the word size and endianness of the host architecture may be different to that stored in the image file.

@igrr My latest commit goes one step further by also taking into consideration the host architecture endianness. I trust that is in the spirit of what you requested. |

... bytes by using CONFIG_SPIFFS_USE_MTIME=1 and CONFIG_SPIFFS_META_LENGTH=4
CPPFLAGS compile flags.
The ESP IDF stores file timestamps in 4 bytes of SPIFFS meta data. By using the above compile flags, this patch restores those timestamps when extracting files from a SPIFFS image file and recreates those timestamps by copying from the sources file(s) when creating a SPIFFS image file.
