IRIG-B implementation

Hello,

I want to synchronize system time of micro controller connected on RS485 line

I want to use IRIG-B for time code which is generated from GPS module.

so far from my study I can transmit IRIG-B over RS485.

Has anyone worked on IRIG-B implementation ?

After I receive the IRIG-B pulse I am not sure how set read and set the system time of UC.
