1. Multi-Time Zone Overview

1. Support for overseas enterprises to store data in local time zones: The system provides configuration options that allow international businesses to store data according to their local time zones. This ensures that overseas enterprises can record and manage data based on their regional time, maintaining accuracy and consistency.

2. Support for overseas users to view data in their personal time zones: To facilitate data review for global users, the system offers a personal time zone setting. Each user can configure their preferred time zone, enabling data to be displayed according to their local time. This enhances usability and efficiency for international users when analyzing data.

2. Key Definitions

1. Time Zone
   A time zone is a region of the Earth that observes a uniform standard time. Due to varying longitudes across countries and regions, local times differ, leading to the division of time zones.
   In principle, the world is divided into 24 time zones, each spanning 15° of longitude and centered on a standard meridian. However, for administrative convenience, countries or regions spanning multiple time zones often adopt a single time standard. For example, China spans approximately five time zones but uses Beijing Time (UTC+8) nationwide for simplicity.

2. UTC (Coordinated Universal Time)
   Coordinated Universal Time (UTC) is the primary global time standard, also known as World Time or International Atomic Time. The acronym UTC is a compromise between English (“CUT”) and French (“TUC”).
   UTC is based on atomic timekeeping while closely approximating Universal Time (UT1). Mainland China follows the ISO 8601-1988 standard (GB/T 7408-1994), referring to it as “International Coordinated Time,” while Taiwan’s CNS 7648 standard uses “World Unified Time.”

3. Local Time
   Local time refers to the time observed in a specific geographic region, determined by its longitude and time zone relative to Coordinated Universal Time (UTC) or Greenwich Mean Time (GMT). It reflects solar time based on Earth’s rotation.
   For example, China operates on UTC+8 (Beijing Time).
