What is a Unix Timestamp?
A Unix timestamp (also known as Epoch time or POSIX time) tracks time as the total number of elapsed seconds since January 1, 1970 00:00:00 UTC, excluding leap seconds. It provides a standardized, timezone-agnostic numeric format widely used across databases, operating systems, and network protocols.

expclaims) in OAuth or JWT authentication headers. - API Date Parsing: Test date formatting and time-zone conversions when sending payloads across distinct backend services.
