Daylight savings time was brought into being in 1917 during World War 1.The time of 2AM was settled on mostly because it would cause the least disruption as most people are asleep at that time. As it is also dark at 2AM most of the world's creatures are also asleep ( the majority population lived in rural areas in 1917 ).
