php - Convert TIMEDIFF to hours plus minutes -

- 

time1: 2013-08-26 16:33:00   time2: 2013-08-26 15:10:00  $query="update `flightschedule`  set delay = minute(timediff(time1, time2))  `flightnum_arr`='".$flightnum_arr."';";

it saves value 23 delay. instead correct answer should 83 minutes. how it?

i think looking for:

$query="update `flightschedule`  set delay = ceil((unix_timestamp(time1) - unix_timestamp(time2))/60) `flightnum_arr`='".$flightnum_arr."';";

alternatively, there time_to_sec function - and, since provides result in seconds, you'll need divide 60 too.

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
