Summertime - time zone change As of March 31, summertime is in effect. That means that the clock in Britain has moved forward 1 hour from GMT and Central Europe has moved forward 2 hours from GMT. Sim Racing Online will stay on the GMT time zone. GMT has not changed. This means that all members have to adjust their calculations for the starting time for all events. Of course, you will only have to do this once to know the difference in time. BST = GMT + 1 hour CEST = GMT + 2 hours For example, if the race starts at 19:15 GMT, then that would be: 19:15 GMT = 20:15 BST 19:15 GMT = 21:15 CEST GMT vs BST converter: https://savvytime.com/converter/gmt-to-bst GMT vs CET converter: https://savvytime.com/converter/gmt-to-cet
