What is the difference between "till" and Until"

[rancher247]

here is a hyperlink to a forum which has a page about the usage of til and until.
please clarify the usage of *until* and *till* (English translation glossary) usage,

[Casiopea]

In addition,

People started spelling till with an apostrophe in the 18th century, indicating they believed it to be a shortened form of until. Although ’till is now nonstandard, ’til is sometimes used in this way. It is a modern invention, dating from 1939, and is considered acceptable. But why bother with apostrophes when you can do without?
