Possible bug in time recording/exporting

I noticed what seems an inaccuracy recording time in gpx exports when the the track passes through the hour 24:00. It seems the day is not incremented as it should. See the example below extracted from a recent Oruxmaps gpx export:
<trkpt ...>
...
<time>2012-05-04T23:59:53Z</time>
...
</trkpt>

<trkpt ...>
...
<time>2012-05-04T00:00:00Z</time>
...
</trkpt>

The second <time> segment (and all subsequent ones) should be "2012-05-05..." and not "2012-05-04..." as we just crossed to the next day.

Is this a known bug?

(btw this was using the latest "donate" version from Android market but I guess it should be the same as the "free" one)
