For the purpose of the SELECT, more unnecessary than anything else. You
would be invoking a transaction for the sole purpose of rolling over a
time value. This as pointed out can be solved without committing a
transaction. For a detailed look at your options see:

http://www.postgresql.org/docs/9.3/interactive/functions-datetime.html#FUNCTIONS-DATETIME-CURRENT

9.9.4. Current Date/Time

It documents the behavior of the various date(time) functions.
