I don't know but could try this like i did. All i know it led a trail back to linux and unix programming. worth a try. worse case it won't tell ya. someone will know though. i went to google and queried just
"date -u +%W$(uname)|sha256sum|sed 's/\W//g'"?
had lots of hits. didn't make sense to me though. maybe something to look at.
the only programming ive done is at the machine level. i have not done assembly in 20yrs.
