Wireless time servicing method, device, and system

A wireless time servicing method applied to a master station in a wireless time servicing system, the wireless time servicing method comprising operations of:

• obtaining absolute time information sent by an external clock source;
• correcting a system time of the master station according to the absolute time information;
• broadcasting path information to a slave station;
• receiving a feedback from the slave station in response to the path information, calculating a transmission path delay between the master station and the slave station, and storing the transmission path delay in time information;
• and
• sending the time information to the slave station;
• wherein the operation of correcting the system time of the master station according to the absolute time information comprises:
• performing atomic clock taming using different taming periods depending on an input signal precision of different external clock sources;
• wherein the operation of performing atomic clock taming using different taming periods depending on the input signal precision of different external clock sources comprises:
• setting the taming period to 5000 seconds when the external clock source is a GPS signal source;
• or
• setting the taming period to 10 seconds when the external clock source is a rubidium clock.
