A wireless access terminal, system and method for the wireless access terminal to synchronize to system times in a wireless communication system. A first timing hierarchy in a first wireless communication network is used to operate the wireless access terminal. The first wireless communication network has a first radio access technology. Operating with the first timing hierarchy includes determining a frame cycle for the first wireless communication network. The frame cycle has a frame cycle boundary. Broadcast parameters for a second wireless communication network having a second radio access technology different from the first radio access technology are received. The broadcast parameters include the system time of the second wireless communication network. The system time of second wireless communication network is aligned, from the perspective of the wireless access terminal, with the frame cycle boundary. The wireless access terminal engages in a communication session using the second wireless communication network.
