Impact of Daylight Savings Time Changes?

Posted by Zonk on from the lots-of-work dept.

jason718 writes "With the pending changes to U.S. Daylight Savings Time, what impact will those changes have to existing systems and their applications? Are some operating systems more open than others with regard to the configuration of Daylight Savings Time start and end dates, or will we need yet another update or patch to modify the internal calendar?"

    With over 800 comments, I thought that's enough to get an idea of its impact and suggestions to deal with it.

    It's Daylight Saving Time, not Daylight Savings Time.

    Cisco devices, both IOS and CatOS based, use the 'summertime' command to compensate for daylight saving time (example [cisco.com]). This means that a change in the DST setup would force you to upgrade code.

    Or at least it would force you to study the command reference a bit better, and find the second optional form of the command that allows you to specify the beginning and end of summertime.

    That would mean you require only a configuration change, and not a code upgrade.
    But of course you would need to read the manual...
