The need for specific timezone information being maintained with  
calendar entries should be considered for all sorts of access and  
synchronising. I access my Kronolith calendar from  
Thunderbird/Lightning by Funambol addon over SyncML. As the Kronolith  
server seems to strip off what is supposed to be represented, in ICS,  
by the "TZID" parameter (as in  
"DTSTART;TZID=Europe/Berlin:20100903T120000"), and to convert all time  
information into UTC values, time representation then won't be able to  
reproduce the original time value under daylight saving time  
conditions after synchronising. Any solution to this should merit many  
thanks of Kronolith users in DST timezones.
