Supports Unix timestamps in seconds, milliseconds, microseconds, and nanoseconds.
Unix timestamps can be represented in various date/time formats. These formats are defined according to standardized rules and are used to consistently convey time data between different systems.
A Unix timestamp is an integer value representing the number of seconds elapsed since January 1, 1970, 00:00:00 UTC. This value allows for numerical calculation of time flow, helping various systems like operating systems, databases, and APIs to efficiently process time data. It is also location and timezone independent.
| Human Readable Time | Seconds |
|---|---|
| 1 hour | 3600 seconds |
| 1 day | 86400 seconds |
| 1 week | 604800 seconds |
| 1 month (30.44 days) | 2629743 seconds |
| 1 year (365.24 days) | 31556926 seconds |
Current 32-bit systems limit the maximum Unix timestamp value to January 19, 2038, at 03:14:07 UTC. Beyond this point, the timestamp will overflow and become negative, potentially leading to system errors or incorrect dates. This is known as the '2038 problem', and transitioning to 64-bit systems is essential to resolve it.
