6 years ago yEnc doesn't store dates. The only file information yEnc holds is the filename, size and CRC32.
Dates only occur in two places:
- NNTP Date header, which refers to the date of posting
- NZB 'date' property, which is just a copy of the NNTP Date header
You could probably stuff the modified time into the Date header, but it's a bit weird, and I doubt any downloader would interpret it at all.
Wrapping it in an archive is the most reliable way to preserve file metadata like that.
Feature request Would it be possible to keep mtime (time of last modification) of the file to be posted? Or is yEnc-encoding always stripping it? I find that metadata useful as it tells the original age of the file.
Possible issues Usenet downloaders such as sabnzbd or nzbget might not handle it correctly. (yEnc-decoding)
Workaround Put the file in an archive before posting. Then mtime of the file is kept.
