Imaginary numbers are defined as the square roots of negative numbers, or as multiples of i, so yes that definition of imaginary time is accurate.
The square roots of negative numbers are different because they are neither rational nor irrational numbers, so they can be combined with real numbers to form complex numbers. Complex numbers are vital to mathematics because they allow you to solve polynominal equations that can’t be solved with real numbers alone, like (x+1)^2 =-9 where x = -1±3i
It’s only relevant at quantum scales, so it’s not something we can experience directly. The super oversimplified version is that imaginary time is what light’s doing while it moves through a medium where it can’t travel at light speed.

Yes. I know. I still don’t know what imaginary time actually means.
That Truro was elected a second time was beyond my imagination, we are living in imaginery time /s
