Need assistance in developing a query to extract minimum response time and its date stamp, maximum response time and its date stamp from sample data below. Ideally when the Response Time is greater than 0 then drops to 0 again.

Ideal output would be:
DEVICE          MIN DATETIME       MIN               MAX DATETIME      MAX
ABCDEF        12/10/2014 17:06     875.0 ms      12/10/2014 16:11      917.0 ms
ABCDEF        12/11/2014 11:26     847.0 ms      12/11/2014 9:31        943.0 ms



Sample data (I out in the '<<<MIN', '<<<MAX' for easier identification)
