Time measurement [..]The main purpose of time is to define with precision the moment of a phenomenon [..]. Time occurrence of the event= EPOCH (date) The definition of time interval is needed. Time interval definition asks for: • Origin to count from Begin of Christian Era • repeatable time interval based on some physical phenomenon At the time being four scales are defined: 1. Sideral time 2. Solar time 3. Dynamical time 4. Atomic time Earth rotation based
