Using POSIX timestamps
POSIX timestamps are a traditional internal representation of time in Unix-based operating systems. A POSIX timestamp is defined as the number of seconds since the epoch, or 00:00:00 Coordinated Universal Time (UTC), January 1, 1970.
Because of its simplicity, this representation is widely used in network protocols, file metadata, or serialization.
In this recipe, we will learn how to convert C++ time points to POSIX timestamps, and create C++ time points from POSIX timestamps.
