<br>
The problem with proposing an official function in a only raw
version is that it becomes a commitment.<br>
Then changing it is more difficult because backcompatibility issues
must be avoided or/and handled.<br>
This is why, to me, it is better to propose such a version on the
fileexchange, that is more informal.<br>

<br>
My PS meant that there is no equivalence of gcf().resizefcn for
zooming. So, recalling labxdtv() must be done <i>intentionnally, by
hand,</i> after zooming or spanning an axes.<br>

<br>
My fault! As aa/bb/cc is in french the common format for dd/mm/yy, I
paid attention only to the first aa/bb, taking them for days/months.
Beside this misunderstanding, the discussion and remarks remain the
same: then we could rather expect majors ticks always on 1st of some
months, and smart subticks accordingly.<br>

Usual commonly spread formats are quite known and shared.<br>
AFAIK, the most standard one is YYYY-MM-DD HH:MN:SS.ssss, with

IMO, the input format should be customizable though an input option
:<br>
<ul>
<li>absolute formats : unix time, julian days, excel time, ... +
linear (s, days, s..) vs vectorized (datenum, etc)<br>
</li>
<li>relative formats (without origin) : in s, mn, h, days<br>
</li>
</ul>
