Timezone: BRT I changed to the default format(yyyy-MM-dd) and the result was correct. I’ve just seen that I was using, I think, a wrong formatting string, dd/MM/YYYY(capital y). My bad, thanks and sorry wasting your time.

It is not unexpected. Looks like default US date/time format. You can change date/time format in preferences. You can also force using “Database native format”.
