That's one way, yes (assuming GNU or BSD date).  You can also get both
times in HH:MM format, and use a string comparison to see which one is
later (greater).

You can only use "local" inside a function, and you haven't shown a
function definition.

Since you want to use a string comparison (your inputs have : characters
in them, and they're composed of base 10 values which may have leading
zeroes), you want < instead of -lt.  In the [[ command, -lt is an
integer comparison, and < is a string comparison.
