You are right. Thanks.

But my event test keeps failing, because of a timezone problem, as  
more debug has shown.

I have this setting in my php.ini:
   date.timezone = "Europe/Madrid"
which is a supported setting (  
http://php.net/manual/en/timezones.europe.php ).

But funambol for thunderbird (Windows desktop) is sending the events  
with another timezone, and if I debug that date comparison in  
kronolith/lib/Api.php  for both date objects, it shows this:

2015-06-22T16:38:50+02:00 WARN: HORDE Caught output:

)

         )
)

Timezone are different, but date are equal, as both timezones are  
GMT+1 (+2 right now in summer).
Once the event has been inserted in DB, the second format is used. The  
former is the new event being inserted by funambol.

Thus, comparing them with "==" return false, while using  
compareDateTime function returns true.

Thanks for your time.
