Timestamp: A timestamp is a numeric value that represents the number of seconds or milliseconds that have elapsed since a specific reference point in time, typically referred to as the Unix epoch (January 1, 1970 00:00:00 UTC). It is often used to store and manipulate time-related data in computer systems.
Date: A date represents a specific calendar day, including the year, month, and day. It can also include the time component, such as hours, minutes, and seconds, depending on the desired level of precision.
Timestamp to Date Conversion: Converting a timestamp to a date involves interpreting the numeric timestamp value and mapping it to a specific date and time representation. This conversion requires considering the reference point (Unix epoch) and applying the appropriate time zone adjustments, if necessary.
Date to Timestamp Conversion: Converting a date to a timestamp involves determining the number of seconds or milliseconds that have elapsed since the Unix epoch corresponding to the given date and time. This conversion also accounts for any time zone differences between the provided date and the Unix epoch.
Unix Epoch: The Unix epoch is a reference point in time commonly used in computing systems. It represents January 1, 1970 00:00:00 UTC and serves as the starting point for calculating timestamps. Many programming languages and systems use the Unix epoch as the basis for their time representation.
Time Zone: A time zone is a region of the globe that follows the same standard time. Time zones are established to ensure consistent timekeeping across different geographical locations. They are defined by the offset from Coordinated Universal Time (UTC) and may involve adjustments for daylight saving time (DST) changes.
