UTC
UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks and time, based on atomic time and adjusted with leap seconds to account for Earth's irregular rotation. It serves as a global reference for timekeeping, replacing Greenwich Mean Time (GMT) as the basis for civil time zones worldwide. UTC is essential for synchronizing time across different regions and systems, ensuring consistency in international communication, computing, and scientific applications.
Developers should learn and use UTC-based time to handle time zones correctly in applications, especially for global systems, logging, scheduling, and data storage, as it avoids daylight saving time ambiguities and local time inconsistencies. It is crucial for distributed systems, financial transactions, and any software that processes timestamps from multiple sources, ensuring accurate and reliable time representation across different geographical locations.
