  The new wave of computing allows users to explore their time in the Internet
of Things (IoT) by connecting their smart devices over the network for data
transfer without human interventions. While this swing increases the pace in
IoT, time synchronization became a demanding feature on IoT devices for
real-time applications. In this paper, we describe two synchronization
protocols in IoT, its features and the advantages over the other. In addition,
this work reveals the importance of time synchronization in the IoT platform
and the effects of bad syncs in real-time applications. We start our research
by analysing the widely using Simple Network Time Protocol (SNTP) and its
performance in terms of offset and delay to examine the accuracy and
reliability to define the synchronization.
