Time values in the API may appear to be different from the time stamps on the eBay.com and the Sandbox. The API returns time-stamps for events and transactions in Greenwich Mean Time (GMT). The eBay.com Web site displays time values in a local time zone. Unless otherwise specified for a particular tag or function, all Time values in the API are in GMT.
If you prefer to display or work with Time values in a particular time zone, your application needs to handle the conversion between GMT and that time zone. Searching for 'time zone' on the Internet will unearth a number of relevant links for determining time-zone conversions.
