He goes at 2:30 and returns at 6:10.

 

Explaination:

 

Since he goes b/w 2 and 3 pm.. therefore the minute hand when he returns will be b/w 2 & 3

abd when he returns b/w 6 & 7 pm..therefore the minute hand when he goes will be b/w 6 & 7

 Therefore the only intersecting time is when he goes at 2:30(2 and 6 have interchanged) exactly.....difficult to explain by writing here really.
