  Log:
    Support %U/%u/%W/%w/%V/%g/%G formats in Time.strptime
    
    Most of these formats were documented as supported, but were not
    actually supported. Document that %g and %G are supported.
    
    If %U/%W is specified without yday and mon/mday are not specified,
    then Date.strptime is used to get the appropriate yday.
    
    If cwyear is specifier without the year, or cwday and cweek are
    specified without mday and mon, then use Date.strptime and convert
    the resulting value to Time, since Time.make_time cannot handle
    those conversions
