class Time
# Returns a new Time where one or more of the elements
# have been changed according to the +options+ parameter.
# The time options (hour, minute, sec, usec) reset
# cascadingly, so if only the hour is passed, then
# minute, sec, and usec is set to 0. If the hour and
# minute is passed, then sec and usec is set to 0.
