📚 Quick Facts

  • The Origin of Time: Standardized time zones were popularized by 19th-century railroads to replace "local solar time," which varied from town to town.
  • UTC vs. GMT: UTC is the high-precision time standard used by modern technology, while GMT is a time zone used in parts of Europe and Africa.
  • Fractional Offsets: Not every zone moves in full hours. This tool accurately calculates fractional offsets for regions like Nepal (UTC+5:45) and parts of Australia (UTC+9:30).
