One exa

Answer 1

This appears to be a unix timstamp with fractions of seconds, in which case....

print date('r', 1334041225.5900);

(it is possible that this numbering system intersects with Unix timestamps at 2012-04-10 09:00:25 +02:00).

See the manual page for the date function for details of specifics.

It's prob ably possible to do the conversion in SQL but you didn't say what type of DBMS this is.
