All our people counter support built-in clock. With GPS or3G/4G, our people counter will correctd every 15minutes, otherwise the time will get much different from the real local time. Many countries have DST and many different time zones, also makes troubles on record time. We usually only use device time as the final time.

Users must make counter connect GPS or 3G. So it will sync time automatically to authority time server by GPS or 3G. The frequency of update is setuped in minutes. Users must setup time server in our BPC client too.
