What is Standard Time (AM/PM)?

Standard time is an essential concept that helps us keep track of the hours in a day and organize our lives. It is also known as regular time, and it refers to the specific times at which clocks in different areas are set. This system was established in 1883 when the International Meridian Conference declared that the world would be divided into 24 time zones, each with its own standard time. Standard time is important for keeping everyone on the same page; it allows us to make sure we are arriving on time for meetings and appointments, and it can have a major impact on how we interact with people around the globe.
