Timestamp to date

Dear All,
I have a property that contains dates in timestamp format,
I tried to convert it to Date Days/Month/Year format with the from_unixtime() function and date()
but it doesn't work.
Any suggestions please?

Hi @Jhony
Please post "Diagnostic Info" from Admin > Troubleshooting, and which database type you are querying.
It looks like the column is a string, not an integer (which stores unix timestamp). You will need to convert it.
