Does the "Time Displacement" property of a wave function have an associated symbol?

Amplitude = $\hat U$

Period = $T$

Ordinary frequency = $f$

Angular frequency = $ω$

Phase = $ϕ$

Time Displacement = ?

The term appears in my college lecture notes:

For this analogy assume $\alpha > 0$.

The author of that text is simply using the term time displacement to mean the time it would take the lagging function to achieve the same $y$ value (displacement, field magnitude etc.) as the leading function.

In that sense $\Delta t$ is not a bad choice for a symbol. Especially considering that distance displacement is commonly represented by the symbol $\Delta x$.

Physicists use $t$ for time, the variable, units second.
