Well, AFAIK there's actually no fundamental reason to apply different
"measuring tapes" to time and space: The constant vacuum speed of light
can serve as a ruler for both, with the distance of a light second
equating a second.
It just happens that it's still more practical to use meters for
space-like dimensions and seconds for time-like dimensions.
