The HTML 5 spec already defines a <time> element in section 3.12.11.
According to the spec, Karl's example would be:

<time datetime="2006-12-04">mardi 4 décembre 2004</time>

Current user agents that do not understand the <time> element will
ignore it, future user agents can get a machine-readable time from the
datetime attribute. The format of the datetime attribute is defined in
section 3.2.3.

The <time> element can be used anywhere inline content is accepted, so
it already works with Simon's <dialog> time stamp idea.
