What Are Floating Times?

Q: What is a "floating time" and how do I handle floating times in my Web application?

A "floating time" or a "floating date" is a time value that isn't tied to a specific time zone.

The Working with Timezones WG Note says:

Some observed time values are not related to a specific moment in incremental time. Instead, they need to be combined with local information to determine a range of acceptable incremental time values. We refer to these sorts of time values as "floating times" because they are not fixed to a specific incremental time value. Floating times are not attached and should never be attached to a particular time zone.

A common example of a floating time value would be a publication date. The January 30, 2013, issue of a newspaper, magazine, or blog posting does not depend on the current local time of the person reading the document. For example, a document might describe its publication date this way:

  Publication Date: <time datetime="2013-01-30">January 30, 2013</time>
