System and method for time synchronization of access devices

A method (200) for synchronizing time of a plurality of access devices (102) in the communication network (110), the method (200) comprising:

• detecting, by way of a control circuitry (104) of a system 100, the plurality of access devices (102) once the plurality of access devices (102) is powered ON by transmitting a status signal (152);
• transmitting, by way of the control circuitry (104), a health message (154) to the plurality of access devices (102) to establish a communication in within the communication network (110);
• reading, local time of by the control circuitry (104) associated with the first access device (102a) from the health message (154) received;
• receiving the health message (154) by the first access device (102a) from the control circuitry (104) and comparing the local time with the time of the controller circuitry (104);
• determining first auto drift correction parameters based on the result of the comparison that is applied to the local time of the plurality of access devices (102) based on the first auto drift correction parameters to generate an intermediate access device time;
• comparing the intermediate device time with the time of the controller clock (107) and determining second auto drift correction parameters based on a result of the comparison;
• applying a second time correction parameters by the control circuitry (104) to the intermediate device time based on the second auto drift correction parameters;
• and
• generating and updating a final device time when a difference between the intermediate device time and the controller circuitry (104) time is above a first predefined threshold value.
