    datetime: Show 12 instead of 0 for 12h hour format
    
    The 12h mode hour format is computed by taking the
    24h mode hour format modulo 12.
    
    The conversion results in 12 noon getting erroneously
    converted to 0.
    
    This commit makes noon get the same special handling
    as midnight.
