Daylight saving time 25 October – member test information

In preparation for the upcoming clock change on Sunday 25 October 2020, IBEX will be offering a test simulation of their auction platform in the member test environment on Friday 16 October 2020.

The transition from summer to wintertime takes place by setting the clock back one hour at 03:00 CET on Sunday 25 October. Therefore Sunday 25th will have 25 trading hours. We encourage customers to use this test to actively place orders and check the results to ensure they are familiar with the process.
