Cookies again: Expiry Date

[stephen barncard]

I've also found that the 'normal' cookie listing in Safari security
preferences is difficult to work with - however *Develop:show web
inspector:storage pane*l shows cookies in a better way and refreshes easily.

For a while I thought my cookies weren't working - but it was because I was
setting the time and date to the current time - and that's the expiration
time and the entries wouldn't appear.

Here's my code for creating the correct format for the date:

<blockquote>

function returnCookieDate pSeconds,pGMTHours
-- returns a date compatible with cookie use:
--              Sun, 5-Sep-2010 15:25:12 GMT
--    requires setOffset, below
      if pGMTHours is empty then put "-0700" into pGMTHours
      if pSeconds is empty
      then
            put the seconds into pSeconds
      end if
      -- add or subtract zone offset (like -0700) from local to GMT in
seconds here
      put setOffset(pSeconds,pGMTHours) into pSeconds
      convert pSeconds to dateitems
      put pSeconds into tDateItems
      convert pSeconds to  internet date  --  like "Sun, 5 Sep 2010 15:25:12
-0700"
      put word 1 of pSeconds into tDay
      put (word 2 of pSeconds) & "-" & (word 3 of pSeconds) & "-" & (word 4
of pSeconds) into tDate
      put word 5 of pSeconds into tTime
      replace space with "-" in tTime
      return tDay && tDate && tTime && "GMT"
end returnCookieDate

function setOffset pSecs,pGMTHours
-- 20100905
-- figures offset for time zone relating to GMT
--     example   pGMTHours = "-0700"
--     pSecs is the time in seconds
      if character 1 of pGMTHours is "-"
      then
            delete character 1 of pGMTHours
            put "-" into pSign
      else
            put "" into pSign
      end if
      put character 1 to 2 of pGMTHours into t6oFS -- chop trailing zeros
      put (t6oFS * 3600) into tOffsetHourSeconds
      switch pSign
            case it is "-"
                  put (psecs - tOffsetHourSeconds ) into pSecs
                  break
            default
                  put (tOffsetHourSeconds  + pSecs ) into pSecs
      end switch
      return pSecs
end setOffset
