Why was daylight savings time put into place during World War 1?

Daylight Saving Time (DST) was implemented during World War I primarily to conserve energy and resources. By shifting the clocks forward, countries aimed to make better use of natural daylight, reducing the need for artificial lighting and saving fuel for the war effort. This practice was seen as a way to maximize productivity and efficiency during a time of resource scarcity. After the war, many countries discontinued DST, but it was reintroduced during World War II for similar reasons.
