public

Creates a new time object with the value given by time, the given number of seconds_with_frac, or seconds and microseconds_with_frac from the Epoch. seconds_with_frac and microseconds_with_frac can be Integer, Float, Rational, or other Numeric. non-portable feature allows the offset to be negative on some systems.
