Why not universal indicator?

You can't use universal indicator for titration because it doesn't give a single, sharp colour change. Simple as that. Nothing to do with time!

Why is it alkaline?

If the electrolysis of a solution (say, sodium chloride) produces a halogen gas (like chlorine), it doesn't produce oxygen. Therefore, hydroxide ions from the water remain in the solution. Lots of hydroxide ions means the solution is alkaline! See electrolysis notes below for more info.
