I am trying to group a list of datetimes by 3 day intervals
<alltimes>
<times dur="PT3H52M" start="2006-01-05T18:49:00" end="2006-01-05T22:42:00" />
<times dur="PT4H16M" start="2006-01-06T19:48:00" end="2006-01-07T00:05:00" />
<times dur="PT3H50M" start="2006-01-08T18:00:00" end="2006-01-08T21:51:00" />
<times dur="PT5H8M" start="2006-01-10T19:51:00" end="2006-01-11T00:59:00" />
<times dur="PT3H39M" start="2006-01-11T19:26:00" end="2006-01-11T23:05:00" />
<times dur="PT3H57M" start="2006-01-12T20:49:00" end="2006-01-13T00:46:00" />
<times dur="PT0H59M" start="2006-01-13T20:51:00" end="2006-01-13T21:50:00" />
<times dur="PT2H22M" start="2006-01-17T00:29:00" end="2006-01-17T02:52:00" />
<times dur="PT3H23M" start="2006-01-17T18:33:00" end="2006-01-17T21:56:00" />
<times dur="PT3H19M" start="2006-01-18T18:36:00" end="2006-01-18T21:55:00" />
<times dur="PT3H19M" start="2006-01-20T18:36:00" end="2006-01-20T21:55:00" />
</alltimes>
How would I group the @start attributes by 3 days?
