Time, in the context of 19th and early 20th-century science and intellectual developments, refers to the evolving understanding and measurement of time influenced by advances in various fields such as physics, astronomy, and philosophy. This period witnessed significant changes in how time was perceived, leading to innovations like standardized time zones, the introduction of the atomic clock, and new theories in relativity that fundamentally altered the scientific community's understanding of time as a dimension in the universe.
