Answer 1

If it’s client side (js) validation you want, and the date string format is as you describe, you can convert that string to a Date and compare that to the current date/time:

var dat      = '12-5-2011 10:51:49',
    datarr   =  dat.split(/\-|\s/),
    chckDate = new Date([datarr[2],datarr[1],datarr[0]].join('/')+' '+datarr[3]);
alert (chkDate < new Date);
