#builtin_call(y = :unset, mo = :unset, d = :unset, h = nil, mi = nil, s = nil, ms = nil) ⇒ Object

when 0 arguments:

return Time.now

when 1 argument:

either an offset in seconds from now, or a Date to convert to a time, or a Time to subtract and return offset in seconds from now
when Numeric : return now + offset in seconds from now
when Nydp::Date : convert date to time
when Time : calculate and return now - Time offset in seconds

when 2 arguments:

first arg is a Time
if second arg is numeric, add to first arg
if second arg is a Time, subtract from first arg
