question about epoch

[Michael Honeyfield <mhoneyfield xtra co nz>]

Hey guys,

Just a quick questions. Can epochs be zero'ed off in a new version e.g:

foo = 12:1.0-17
foo = 0:2.0-1

or are you stuck with it forever? 

Thanks in advance.

Mike

It's perfectly fine to use the name of you pet or child as a password.
How ever, for the sake of security, make sure the names of all your pets
and children contain several non-alphanumeric characters.
