$ fq -h zip zip: ZIP archive decoder Options ======= uncompress=true Uncompress and probe files Decode examples =============== # Decode file as zip $ fq -d zip . file # Decode value as zip ... | zip # Decode file using zip options $ fq -d zip -o uncompress=true . file # Decode value as zip ... | zip({uncompress:true}) Supports ZIP64. Timestamp and time zones ======================== The timestamp accessed via .local_files[].last_modification is encoded in ZIP files using MS-DOS representation (https://learn.microsoft.com/en-us/windows/win32/api/oleauto/nf-oleauto-dosdatetimetovarianttime) which lacks a known time zone. Probably the local time/date was used at creation. The unix_guess field in last_modification is a guess assuming the local time zone was UTC at creation.
