Inmediateness

Some postings ago, there where a little discution of how tense is used to
mean urgency

For example in English:
  I'm out of here. (meaning "I will leave at once").

In Spanish, at least in my dialect, one would say
  Ya me fui'. (lit: I'm already gone)

Question: how is used in other languages (conlangs and natlangs) tense in
orther to mean urgency.
