It's expected that the function's creator is responsible for properly
marking its stability. This allows some flexibility when you know more
than the system does (for example, a

Check your version with:
select version();
In the meantime, you could try
date_part('epoch', submittime)
which will return a unix timestamp, you could then use functions within

date),'DD/MM/')
