If I remember ok it is the time it takes to reach 80% of the

Actually (1− 1/e) (approximately 63 percent)

Also, the time constant of the electronics is after mechanical lags, so the delay may be somewhat longer.

And then there is the time constant of the glider, which does not reach a steady
upward speed immediately; ie, the glider is a mechanical filter for lift with, I'm
guessing, a time constant between 1 second (low wing loading with stiff wings) and
3 seconds (high wing loading with bendy wings). Jon may have included the glider
lag in his "mechanical lags".
