    Bugzilla 790526 Correct weeknum calculator
    
    This change will fix 'num-of-weeks-since-1/jan/1970' which formerly used quotient to remove
    the fractional part of the division. For negative values of num-of-weeks, the number is truncated
    in the wrong direction (i.e. towards 0). This change uses floor instead to ensure the num-of-weeks
    found is the nearest integer LESS than the fractional number.
