Obviously having 3:30 pm suddenly become the middle of the night would be bad, but we&amp;#x27;re talking a delta of 18 seconds spread over
almost 50 years... hardly big enough to be called &amp;quot;out of sync&amp;quot; in any noticeable sense. Maybe in a millennium or two we&amp;#x27;ll lose the cultural context of what &amp;quot;it&amp;#x27;s 5:00 somewhere&amp;quot; meant, but I&amp;#x27;m sure the historians could add a blurb.</text><parent_chain><item><author>FabHK</author><text>What we&amp;#x27;d like to have:&lt;p&gt;1.

This doesn&amp;#x27;t make a lot of sense; on March 1st, we don&amp;#x27;t start pretending that February 29th never happened.</text><parent_chain><item><author>FabHK</author><text>What we&amp;#x27;d like to have:&lt;p&gt;1.
