Most of Europe will put their clocks forward by one hour in the early hours of this coming Sunday morning (27th March). If you are the host of a league in a region that observes DST and you want to race at the same time on Sunday 27th March (and beyond) as you did today...
Before your league race on Saturday 26th March (or if you don't race every day, more than 24 hours in advance of the start time of your race on Sunday 27th March) you should go to Edit League / Schedule and adjust the race time 1 hour backward.
I realise many of you already know this but in conversations I have had with a number of league hosts there remains some confusion as to when the changes need to be made and in which direction the race time should be adjusted.
I hope this helps.
