Hi, I am Nirav from the Java Technology Centre, IBM. I am working for the L3 team here. Sometime back, one of my colleagues Amar Devegowda, had mailed regarding updation of the DST rules for Istanbul,Turkey. Actually as per the current rule that is being used in the JVM Daylight saving was supposed to start at 3.00AM . But as per the latest rule from the below link, Daylight timings start from 1.00AM. We were asked to provide an official link where these changes were stated. I hope this link will serve the purpose so that the database can be updated with the latest DST rules for Istanbul. http://wwp.greenwichmeantime.com/time-zone/europe/european-u nion/turkey/ Please do contact me for any further queries that may be there.
