I may be missing something here, but... EST is UTC-0500, and CEST is UTC+0200. The difference between the two is therefore 7 hours, which is what the above shows. Are you perhaps confusing the meanings of the "S" in each of the abbreviations? While CEST is Central European Summer Time - i.e. observing daylight savings - EST is Eastern _Standard_ Time, i.e. _not_ observing daylight savings. The equivalent of CEST for the Eastern timezone is EDT. Regards, Adam
