An inside source tells you when TSHTF!

If you had an inside source tell you when the SHTF, what would you do with your time to prepare?

The type of SHTF is your choice it can be anything from Rage Virus all the way to Alien Invasion or Demons coming from hell.

For example:
1 day till a terrorist blows up Washington DC.
2 weeks till a Caldera erupts.
6 months till your government collapses on itself.
1 year till people raise from the dead.
5 years till a meteor strikes the Earth.
etc, etc...
