Why OS Patching For Timezone Changes Is A Bad Idea

Discussion in 'NZ Computing' started by Lawrence D'Oliveiro, Mar 30, 2011.

  1. Here we go again, another change to daylight-saving rules in some part of
    the world throwing users of proprietary OSes into a panic
    <http://www.theregister.co.uk/2011/03/29/chilean_clocks/>.

    The Olson database hasn’t officially been updated yet
    <http://www.twinsun.com/tz/tz-link.htm>, but what’s the bet they’ll be well
    in advance of Microsoft and others having to rush out patches?

    Yes Lawrence, it is really difficult to change a Windows timezone:

    - Download tzedit.exe (or get it off your Windows install disks)
    - Run it and change the offending time zone. Even a Linux head could
    do this.

    Or you could follow the several methods documented in
    http://support.microsoft.com/kb/914387

    Now where did you say the Linux patches are??

    Mostly on the repository sites. Mostly they have the patches for the OS
    and for Java too, but I doubt that they'd have them yet. I'd say that it
    wasn't a problem for either OS, unless of course you live in Chile or
    deal with people or firms in Chile.

    In both OSes there are manual ways of editting timezones as you point
    out. But some of our older OSes never get patched for timezone changes
    and no planes have yet fallen from the skies. That article that Lawrence
    references is obviously a joke.

    Cheers,

    Could you roll that out en masse via a GPO, by any chance?

    Or doesn’t Microsoft’s legendary system integration extend that far?

    AD GPO System integration only works for Microsoft software (or other
    software) that uses APIs designed to allow the software's local interface
    to be overrode by control from Microsoft AD or Samba.

    The key is "designed to allow" control. GPO is not a guaranteed absolute
    means to manage applications of MS Windows, and not all instances of MS
    Windows crippleware will even allow connection to an AD Domain - it all
    depends on the degree that Microsoft has crippled it.

    It's either "overrode" or "overridden".

    Now that I think about it, it should be "overridden" - the passive past
    participle.

    Or, if you prefer downloading everything again to applying a patch:
    <ftp://elsie.nci.nih.gov/pub/>.

    So where are those Apple and Microsoft patches, then?

    Easy as, on Windows...


    1) Download the Windows tzedit utility from Microsoft.

        <http://download.microsoft.com/download/5/8/a/58a208b7-7dc7-4bc7-8357-28e29cdac52f/tzedit.exe>


    2) Run tzedit, select time zone "(UTC-04:00) Santiago", and click "Edit"

    <http://i52.tinypic.com/66el8g.png>


    3) Make sure the last day for daylight saving is set to the
    first Saturday of May.

    <http://i54.tinypic.com/20093dy.png>


    No problem!!!

    Well, actually, the above is the hard way to do it. MS provides a
    program that you just run and it does all that. It includes all the
    latest updates. Or you could just wait for the patch.

    Taking the /what/ ("roll that out en masse") separately from the /how/
    ("via a GPO")...

    Any company with a competently-managed PC network should be able to roll
    out updates including daylight saving changes.

    Microsoft's web site has examples of scripts for rolling out daylight
    saving changes.
