Just a memo. Here below the link of the correct procedure to realign data during daylight time on and off. Literally a life-saver, especially for anybody working from a different time zone then CME.
There's absolutely nothing to do regarding daylight saving times.
Unless you have a parameter in a strategy which is using your local time, and you're in a time zone with a different start date than the country of your instrument's exchange (a strategy with in European time zone trading CME instruments for example, as the US goes in summer time on March 12, vs March 26 in Europe).
