running a process (oracle db) with modified system time

hello there,

I'm wondering if there is a way to run a process on solaris in such a way that it receives the system time modified with a given amount of secs/mins/hours/...

I don't want to change the time on the server, I just want to run a specific process in an environment that "emulates" a different time.

is it possible to write some piece of code that catches some syscalls and returns modified time? if it is, how can I do that? any hints/links/code examples ;) will be greatly appreciated.

the "process" is in fact an oracle database instance, so the solution
(if any) would have to be a really good one :)
(that is, on proper level of interception to make sure that any syscall
that is supposed to return a current time is intercepted consistently)

regards,
