If you're looking for differences that could be spotted by $(date) (so, 
things that take multiple seconds to run), you might try just running 
with tracing enabled:

zsh -x

The commands are output before they're run, so if you end up with:

+.zshrc:123> some long running command

You can probably just eyeball it.
