Capital Spreads sent out another email after the one quoted above, in which they say: "As the US are not due to adjust their clocks until Sunday 4th April, we will be closing one hour later at 22:15 during this interval (Monday 28th March - Friday 1st April). The trading hours for our markets will adjust accordingly during this period to reflect this temporary adjustment. Please note that we will be open on Monday 28th March between 14:00 - 22:15 and NOT 13:00 - 21:15 as previously stated."
