if u dial a number.. the person picks and disconnect the call.. does it show as 0 second call or 1 second call?? If i am not wrong
Nokia shows 1 second after the second is over i.e if it's a 10.1 seconds call (technically 11th second running) then also it would be shown as a 10 second call in the log.
maybe u should try a 20 and a 30 second call if still 21 and 31 paise get deducted then i think this logic works.
u r correct on that..
what happens is that if the cell says that duration is 20sec, actually 20sec have been completed and 21 sec is going on
like, if u say tht ur age is 18yrs, u may actually be 18yrs and 1 day old or 18 yr and 300 days old, but its still said as 18 yrs(as the least count would be taken as years, if it was taken as months or days , a similar example would apply)
similarly, the 1 second least count was OK for a 1 min pulse and even for 10 min pulse, as an error would occur at every 60 or 600 seconds and an error of upto 1 sec in 60 or more seconds is acceptable
the same is not valid with a 1 sec pulse, and what is needed is a least count in ms so that there is accuracy in the counting of seconds.
however, as the losses of the per second error are small, and the cost of implementing the ms accuracy will be high, it is better that it not be implemented as that would cause rate increases.
