If you can assume unix time, the following seem to work:


local epoch =  {year=1970, month=1, day=1, hour=0, min=0, sec=0, 
isdst=false }
function gmtime(t)
  t.isdst =  false
  return os.time(t) - os.time(epoch)
end


For os.time(t) I found that t.isdst=false means force 'no DST', while 
t.isdst=nil means assume DST as known for that day. Perhaps a note in 
the Lua reference manual would be good?
