RE: Oracle as a "time machine"

["Dunbar, Norman" <norman.dunbar@xxxxxxxxxxxxxxxxxxxxxxxxx>]

In a past life, a company I worked at had a stored proc in the database
to return the SYSDATE. Seemed a bit of overkill, but it allowed the
system to roll forward (and back) to any date we cared to have it at
without changing the server time or using the Oracle fixed date (which
never rolled onwards - it simply remained fixed.

There was a table in the schema which held an indicator of whether we
were using SYSDATE or pseudo-date and a column holding a positive offset
from SYSDATE that would be added to SYSDATE when the function was
called.

The app was a financial one and it was easy to use this system to roll
dates forward and see how a finance contract worked out over 'three
years' rather than over a real three year period.

Might not be useful to the OP, but a thought maybe?


Cheers,
Norman.
