<div>There is an ambiguity in the original TrueType spec that has, unfortunately, continued right up to this latest OFF spec. Specifically, in the 'head' table, the "modified" and "created" fields are listed as 64-bit counts of seconds since an epoch of "12:00
midnight, January 1, 1904". Unfortunately no time zone is specified, and this has led to ambiguity where a font is modified by some tool in, say, Germany, and is then run through validation code in California, where a complaint is raised that "the modification
date is in the future".</div>
<div><br>
</div>
<div>I wonder if it would be possible to include a clarifying note in the spec that GMT/UTC is the time zone of choice for these fields?</div>

<p class="MsoNormal">Dear AHG members,<o></o></p>
<p class="MsoNormal"><o> </o></p>
<p class="MsoNormal">I am happy to report that the text of the 3<sup>rd</sup> edition of ISO/IEC 14496-22 “Open Font Format” standard has been promoted to Draft International Standard stage and the ballot is now published. The text has been made public and
can be downloaded for review using the following link:<o></o></p>
<p class="MsoNormal"><a href="http://mpeg.chiariglione.org/standards/mpeg-4/open-font-format/text-isoiec-dis-14496-22-3rd-edition">http://mpeg.chiariglione.org/standards/mpeg-4/open-font-format/text-isoiec-dis-14496-22-3rd-edition</a><o></o></p>
<p class="MsoNormal"><o> </o></p>
<p class="MsoNormal">The AHG mandate is “to study the DIS of the ISO/IEC 14496-22 3<sup>rd</sup> edition and solicit technologies to further improve it”. I would like to ask you to review the text and provide your suggested changes which can be incorporated
as ISO ballot comments. At this stage, we can only suggest comments that incorporate clarifications and improvements to what is already included in the standard, proposals for new technologies can be considered as future new work items and would require an
amendment.<o></o></p>
<p class="MsoNormal"><o> </o></p>
<p class="MsoNormal">Thank you very much for your contributions!<o></o></p>
