Best practice
In formal writing, consider using "Prior to that time" for a more sophisticated tone. However, "Until that time" is perfectly acceptable in most contexts.
Common error
Avoid using "while that time" when you mean "Until that time". "While" implies simultaneity, whereas "until" indicates a duration leading up to a specific point. For example, say "We will wait until that time comes" not "We will wait while that time comes".
