Hi Anne-Marie The data that I pulled off the Columbus Coromandel, DDGY.104 has some date oddities. As of April 1, the computer labled all data 1 week later. So Apri 1sts xbt data reads April 8 on both the header and the date stamp from DOS. According to the officers it continued like that for the rest of the voyage. When I saw them yesterday, the computer was reading the correct date... Strange. Thx Carrie
