Just to update this, the time stamps now appear to be 5 hours ahead of US Eastern time. I started this thread on March 28 which is one day before the UK went on British Summer Time, the UK's equivalent of Daylight Savings Time. That tells me that the time stamps are on British time, not Greenwich Mean Time which does not change when the UK goes on BST. There is about a two week difference between US Daylight Savings Time and BST so that is why at the time this thread was started, there was only a 4 hour difference instead of the usual five. If anybody really cares.
