From docs:
It is quite important to realize that CURRENT_TIMESTAMP and related
functions all return the time as of the start of the current transaction;
their values do not increment while a transaction is running. But
timeofday() returns the actual current time.
CURRENT_TIMESTAMP = now() = timestamp 'now'
