I got this function off of this site from an expert but it's flawed.

For example:

  12:00 AM is returning 12:00, when it actually should be returning 00:00.
  It's pretty screwed up.. I can post my conversion code for doing Military to Standard if that helps.
  Thanks

function to_military( val )  {            
    var pm = 0, hour = 0, min = 0;
    if( val.search( /PM/i ) >= 0 )
        pm = 12, val = val.replace( /PM/i, "" );
    if( val.search( /AM/i ) >= 0 )
        val = val.replace( /AM/i, "" );
    var vals = val.split( /[^0-9]+/ );
    hour = parseInt( vals[ 0 ] );
    if( hour > 24 ) hour = 0;
    if( hour <= 12 ) hour = ( hour + pm ) % 24;
    if( hour < 10 ) hour = "0" + hour;
    min = ( vals.length > 1 ) ? parseInt( vals[ 1 ] ) : 0;
    if( min < 10 ) min = "0" + min;
    return hour + ":" + min;
}


Here's some easy test code to copy/paste so you can test.

    if( val.search( /AM/i ) >= 0 )
        val = val.replace( /AM/i, "" );
    var vals = val.split( /[^0-9]+/ );
    hour = parseInt( vals[ 0 ] );
    if( hour > 24 ) hour = 0;
    if( hour <= 12 ) hour = ( hour + pm ) % 24;
    if( hour < 10 ) hour = "0" + hour;
    min = ( vals.length > 1 ) ? parseInt( vals[ 1 ] ) : 0;
    if( min < 10 ) min = "0" + min;
    return hour + ":" + min;
}

You don't need to do all that. This is much simpler...

var dt = new Date("1/1/2000 " + val);
var hour = dt.getHours();
var min = dt.getMinutes();
etc.  

And it even validates whether the time is a valid time string.
