clock synchronization gained momentum in the recent years and became a part and parcel in the deferents distri- buted system including wireless sensor network, and extended its application to a sundry of industries and application fields such as military, medical, transportation to name a few. This article propose an in depth study and analysis of the different problems and hardware limitations that may be encountered and lead to the malfunctioning or non-accessibility to seamless Wireless network, hence, putting its uptime reliability in jeopardy. This paper emphasis the role of clock synchronization in a number of fundamental operations that enhances the stability between sen- sors and ultimately increase the lifetime and stability of wireless sensor networks. In addition, it provides an insight and reference guide for future researches to tackle time synchronization issue from a different angle(Clock drift) to suggest a practical and viable trouble shooting guides and solutions. Key Words : Clock synchronization, Wireless Sensor Network, Synchronization Problem.
