Are you getting the actual value "2000-01-01 03:02:16.105976+03"
or is that just a hypothetical example to show that the value doesn't
change? If the latter then see the comments about current_timestamp
in the documentation:

http://www.postgresql.org/docs/8.1/interactive/functions-datetime.html#FUNCTIONS-DATETIME-CURRENT

"It is important to know that CURRENT_TIMESTAMP and related functions
return the start time of the current transaction; their values do
not change during the transaction. This is considered a feature:
the intent is to allow a single transaction to have a consistent
notion of the 'current' time, so that multiple modifications within
the same transaction bear the same time stamp."
