Flashtime

Speed Force sharing, nicknamed by Cisco as "Flashtime", is the ability to share the Speedsters' speed with other persons who isn't/is speedster. This ability also lets other people converse with them at their heightened speed.

Speed Force sharing also bolster another speedster's speed by running in front of him/her. The only ones who can do that are Allen Barry Allen/The Flash and Jay Garrick. But, Jay Garrick can't let other people converse with him at his heightened speed.
