Need to know Joomla Session timer data type -

-

i have been looking under database of joomla. there found under gu94g_session table, time column having value 1377499731. mean. how can decode time. appreciate help.enter image description here

the time column contains unix timestamp @ time of records creation.

in joomla! 2.5+ , 3.x+ time column of #__session set value returned php's time() i.e. current unix timestamp.

when sessions stored in database, /libraries/joomla/sessions/storage/database.php file creates record using sql query:

        $query = $db->getquery(true)             ->update($db->quotename('#__session'))             ->set($db->quotename('data') . ' = ' . $db->quote($data))             ->set($db->quotename('time') . ' = ' . $db->quote((int) time()))             ->where($db->quotename('session_id') . ' = ' . $db->quote($id));

the time set line:

->set($db->quotename('time') . ' = ' . $db->quote((int) time()))

(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...
