Convert a date-time to Unix epoch seconds.
It combines Year, Month, Day, Hour to estimate Unix Timestamp.
Formula & Method
Core equations: Unix seconds: ts=\left\lfloor\frac{t_{UTC}-1970 ext{-}01 ext{-}01T00:00:00Z}{1s}\right\rfloor.
Notation used in the formulas: R = Unix Timestamp; x_{1} = Year; x_{2} = Month; x_{3} = Day; x_{4} = Hour; x_{5} = Minute.
Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.
