from my understanding Knime works in UTC. However, when I import data it mostly does not have a timezone indicator (e.g. CET) the conversion node assumes that the time zone is in UTC. This is wrong with data in local time and can be seen when data is exported with timezone indicator.
I think it would be a good idea to add: "String to Date/Time Node" add option "Assume Local Time Zone". This could be a checkbox: Assume string to be in local time, and in brackets the setting taken from user.timezone variable. What do you think?
Currently I help myself by using a Java snippet to replace the "String to Date/Time Node".
