timespan working correctly implementation wrong.

first fault: a/60 return integer instead of double. second fault: new timespan(h,m,s,ms) expects integers

the reason code compiles because compiler rounding on a/60 if change a/60 a/60d (d decimal) correct division compiler error. due integer limitation.

to fix error make division total number of seconds , (new timespan()).addseconds(your number);
