Canon WFT-R10A Wireless File Transmitter for EOS R5 C & R5 Mirrorless Camera - Manual (Page 136)

Synchronizing the Camera Time
You can synchronize the time for multiple EOS R5 cameras with WFT-R10 attached.
The camera that sets the time to synchronize is called the “sender camera,” and the camera
that synchronizes with the time of the sender camera is called the “receiver camera.”
Up to 10 receiver cameras can be synchronized.
• Preparing for Time Synchronization
• Synchronizing the Time
Caution
Make sure to perform time synchronization on cameras of the same model.
Synchronizing the time on receiver cameras is not possible with different models of
the sender and receiver cameras.
Note that even after synchronization, a slight margin of error applies between
sender and receiver camera time (of ±0.05 seconds, at most).
