Can I get close enough chart without birth time?

I'm trying to figure out someone's chart. I know all but birth time. Would I still get some of the houses correct?

I thought you needed birth time for the ascendant, and without that you can't get the houses. Someone else might know better than I, but that's my understanding.

No. Sorry. You can check at astro.com, for instance, how much everything changes if you put in different times. You could possibly even get different signs on some planet(s).

Birth chart rectification.
