1. Multi-Time Zone Overview

1. The system supports storing data using the local time zone for overseas organizations: The platform provides settings that allow overseas organizations to store data according to their local time zone. This enables recording and managing data based on local time, ensuring accuracy and consistency.

2. The system supports users viewing data in their personal time zone: To facilitate data viewing for overseas users, the platform offers personal time zone settings. Each user can set their own time zone so that data is displayed according to their local time. This makes it easier for users to interpret and analyze data and improves productivity.

2. Terminology

1. Time Zone
   A time zone is a geographic region that uses the same standard time. Because countries and regions span different longitudes, local times vary, so the world is divided into multiple time zones. In principle, the globe is divided into 24 time zones, each spanning 15° of longitude with a central meridian. In practice, some countries or regions span multiple theoretical time zones but adopt a single official time for administrative convenience. Therefore, time zone boundaries often follow political or natural features rather than strict meridians. For example, although China spans roughly five theoretical time zones, it uses a single standard time (UTC+8), commonly known as Beijing Time.

2. UTC (Coordinated Universal Time)
   Coordinated Universal Time, abbreviated as UTC, is the primary time standard by which the world regulates clocks and time. UTC is based on atomic time and is adjusted to remain close to mean solar time. Different language abbreviations (e.g., CUT in English, TUC in French) led to the compromise abbreviation UTC. In technical standards, UTC is used as the global reference for date and time representations (e.g., ISO 8601).

3. Local Time
   Local time refers to the time observed at a specific geographic location, determined by that location’s longitude and time zone relative to the global standard (UTC). It represents the actual civil time for daily activities at that location. For example, China’s local time is UTC+8.
