Mexico
A new time zone, “Eastern Standard Time (Mexico),” was added in KB 3039024. It was originally set to observe DST from the first Sunday of April through the last Sunday of October. However, according to the latest announcement from the Mexican government, this time zone does not observe DST. Therefore, the previous DST rules for this time zone are removed in this update.
