Hmm. I don't have any such events, apparently. But comparing the new
importer with the old, I did find something that looks odd:

Old:

-  <divecomputer model='Uemis Zurich'>
-  <event time='18:25 min' type='4' flags='1' value='5070' name='ceiling' />
-  <event time='18:25 min' type='1' value='60' name='deco' />
-  <event time='18:30 min' type='4' flags='2' name='ceiling' />
   <event time='19:10 min' name='Tank Pressure Info' />
-  <event time='19:31 min' type='4' flags='1' value='3090' name='ceiling' />
-  <event time='19:31 min' type='1' value='60' name='deco' />
   <event time='21:55 min' name='Speed Alarm' />
-  <event time='23:20 min' type='4' flags='2' name='ceiling' />

New:

+  <divecomputer model='Uemis Zurich' deviceid='e0484cf9' diveid='00000009'>
+  <event time='18:25 min' type='1' value='3932165' name='deco stop' />
   <event time='19:10 min' name='Tank Pressure Info' />
+  <event time='19:31 min' type='1' value='3932163' name='deco stop' />
   <event time='21:55 min' name='Speed Alarm' />

So the "ceiling" and "deco" events have gone away, and replaced with
"deco stop" events that have some insane - and unexplained - value
associated with them. It looks like it's two 16-bit values encoded
into one 32-bit number. Ugly. Not that the old events were any
prettier. What does the value mean there? Who knows..

Anyway, apart from some changes like that, the main change is just
that the new importer adds the deviceid and diveid fields. nd
apparently we round the duration up to even minutes these days.

Interestingly, the dive starting time seems to fluctuate by one second
too when I compare the old and the new import. Is the uemis also doing
some odd "relative date" thing where the time of the importing
computer will affect the dive time?
