Unix time
The number of seconds since the Unix Epoch (1-1-1970).
Originally unix time was stored as a 32-bits integer which limits the time to reaching 19 January 2038 03:14:07 UTC [1]. Modern computers use a 64-bit field that expands the maximum time far beyond the expected lifetime of the universe.
