Not to my knowledge.
Are you using or are you going to use an RGB2HDMI?
It might be possible to set up a time server on the RPi and connect the serial port to the Amiga. You'd need a application on the Pi and one on the Amiga and be using an RPi that has Wifi.
Other than that you'd be looking at a
PlipBox which would connect to the parallel port or a
Wifi232 which connects to the serial port.
