<p class=big-issue>...
<p>The <code><a href="#input0">input</a></code> element represents a
control for setting the element's <a href="#value12"
title=concept-fe-value>value</a> to a string representing a <span>date and
time</span>, with no time zone information.

<p>If the element is <i title=concept-input-mutable><a
href="#mutable">mutable</a></i>, the user should allow the user to change
the date and time represented by its <a href="#value12"
title=concept-fe-value>value</a>, as obtained by <span title="parse a date
and time">parsing a date and time</span> from it. User agents must not
allow the user to set the <a href="#value12"
title=concept-fe-value>value</a> to a string that is not a <span>valid
date and time</span>. If the user agent provides a user interface for
selecting a date and time, then the <a href="#value12"
title=concept-fe-value>value</a> must be set to a <span>valid date and
time</span> representing the user's selection. User agents should allow
the user to set the <a href="#value12" title=concept-fe-value>value</a> to
the empty string.

<p><strong>The <a href="#value8">value sanitization algorithm</a> is as
follows:</strong> If the <a href="#value12"
title=concept-fe-value>value</a> of the element is not a <span>valid date
and time</span>, then set it to the empty string instead.

<p>The <code title=attr-input-min><a href="#min2">min</a></code> attribute,
if specified, must have a value that is a <span>valid date and
time</span>. The <code title=attr-input-max><a href="#max4">max</a></code>
attribute, if specified, must have a value that is a <span>valid date and
time</span>.

<p>The <code title=attr-input-step><a href="#step0">step</a></code>
attribute is expressed in seconds. The <a href="#step-"
title=concept-input-step-scale>step scale factor</a> is 1000 (which
converts the seconds to milliseconds, as used in the other algorithms).
The <a href="#default2" title=concept-input-step-default>default step</a>
is 60 seconds.

<p>When the element is <a href="#suffering3">suffering from a step
mismatch</a>, the user agent may round the element's <span
title=concept-input-value>value</span> to the nearest date and time for
which the element would not <a href="#suffering3" title="suffering from a
step mismatch">suffer from a step mismatch</a>.

<p><strong>The <a href="#algorithm5"
title=concept-input-value-string-number>algorithm to convert a string to a
number</a>, given a string <var title="">input</var>, is as
follows:</strong> If <span title="parse a date and time">parsing a date
and time</span> from <var title="">input</var> results in an error, then
return an error; otherwise, return the number of milliseconds elapsed from
midnight on the morning of 1970-01-01 (the time represented by the value
"<code title="">1970-01-01T00:00:00.0</code>") to the parsed date and
time, ignoring leap seconds.

<p><strong>The <a href="#algorithm6"
title=concept-input-value-number-string>algorithm to convert a number to a
string</a>, given a number <var title="">input</var>, is as
follows:</strong> Return a <span>valid date and time</span> that
represents the date and time that is <var title="">input</var>
milliseconds after midnight on the morning of 1970-01-01 (the time
represented by the value "<code title="">1970-01-01T00:00:00.0</code>").
