Timezone difference #15
Description
I have used this code in 2 different site which sits in 2 different server with a time difference of 1 hr and the code generated in my mobila app matches with one server (both are in same timezone) and 2nd one site doesnt match the code at all but matches after an hour. (Note i have generated 2 different secret keys and mobile app has 2 different accounts respectively).
How to work this out?
