About Time Systems
Time systems are standardized methods for measuring and representing time. Different time systems are used in various contexts, from everyday life to specialized scientific and technical applications.
Understanding Unix Epoch Time
Unix epoch time (also known as POSIX time or Unix timestamp) represents the number of seconds that have elapsed since January 1, 1970 (UTC), not counting leap seconds. It's widely used in computer systems and programming as a standard way to represent time.
Coordinated Universal Time (UTC)
UTC is the primary time standard by which the world regulates clocks and time. It's essentially the same as Greenwich Mean Time (GMT) but is measured using atomic clocks for greater precision. UTC is not adjusted for daylight saving time, making it a consistent reference point for time calculations.
Local Time
Local time is the time observed at a specific location, adjusted for the location's time zone and possibly for daylight at a specific location, adjusted for the location's time zone and possibly for daylight saving time. It's the time we use in everyday life, but it varies across different geographical locations.
