Can we trust time.delta_seconds() ? #2

I had a look at the code for bevy_ggrs, and the Time resource seems unmodified by bevy_ggrs (the Time resource just updated by bevy.)

Since two machines could have a different frame rate. I'm guessing we can not rely on time.delta_seconds() for movement. Otherwise the same object will move by a different amount on each machine.

Nevermind, just saw GgrsTimePlugin.
