I'm writing an SSIS Package to take data from a production DB to a reports server/data warehouse. The other databases on my reports server are all in Mountain Time but this DB is in UTC should I convert the data as I'm importing it with SSIS, or should I leave the data as is and just keep track of what time zone the server data is in and deal with it in my queries? Is there a reason not to convert the data as I copy it over?
