Assuming you have your string in cell A1, the following formulas will give you:
Excel date ad time =--SUBSTITUTE(SUBSTITUTE(REPLACE(A1,7,0,", "),"AM"," AM"),"PM"," PM")
Excel date =INT(SUBSTITUTE(SUBSTITUTE(REPLACE(A1,7,0,", "),"AM"," AM"),"PM"," PM"))
Excel time =MOD(SUBSTITUTE(SUBSTITUTE(REPLACE(A1,7,0,", "),"AM"," AM"),"PM"," PM"),1)
