Seetting the Time Zone for your Server

Configure->LocalConfig->TimeZone

The internal clock of your Server is configured to run Universal Common Time (UCT), which can be thought of as much the same as GMT, and so does not incorporate daylight savings (summer time) and does not take into account latitude. Setting the local time zone here will adjust the time displayed by the server to take account of where you are in the world and whether and when you change your clocks for daylight savings.

In the Local category of the Configuration section you can change which time zone this Server thinks it is in, the default is "GB-Eire", which will switch to BST (British Summer Time) automatically when the clocks change. This switching is also know as daylight saving time.
