My own log seems to actually have aritime properly but for some reason
this event is not shown on the graph:
<event time='78:54 min' type='21' flags='1' name='airtime' />
<event time='78:57 min' type='21' flags='2' name='airtime' />
The guy who reported the issue has a different case, and it might be
that the newer models of Suunto have changed something. Looking into
the DM5 database, it seems that the event number there is 37 (0x25),
that is already parsed properly on DM5 DB import. I'll ask for a
memory dump of the D6i so we get the facts and don't need to wonder if
DM5 did something in-between.
