Note that I haven't read the actual standards document. But if that is the case, then how can the following be valid formats according to Markus Kuhn's document (which w3.org links to, btw)? <quote> This means that the following two notations refer to exactly the same point in time: 1995-02-04 24:00 = 1995-02-05 00:00 </quote> > > Please consider removing the `T' from the iso_format_strings. > > That seems a bit extreme, for backward-compatibility reasons.
