    $\begingroup$ Can you give that second dataset in InputForm so that we don't need to keep it in text format? $\endgroup$

Assuming that the days and times in the gathered data list are strings you could do something like

days = {"Monday", "Tuesday", "Wednesday", "Thursday", "Friday", 
   "Saturday", "Sunday"};

data2 = Reap[
    Sow[(AbsoluteTime[#2] - AbsoluteTime["00:00:00"])/3600., #1] & @@@
      Flatten[data, 1],
    days, #2 &][[2, All, 1]];

Show[BoxWhiskerChart[data2],
  FrameTicks -> {Thread[{Range[7], days}],
   {#, IntegerString[#, 10, 2] <> ":00"} & /@ Range[0, 24, 4],
   Thread[{Range[7], ""}], Thread[{Range[0, 24, 4], ""}]}]
