When i use this formula in a datasets field:
DATE_FORMAT(Fecha, ‘%b’)
I get “jan” instead “ene”. ¿how to change the output to spanish?
thank you
@Peter help please 
You should use $dateFormat in the formula string.
Assuming that Column Fecha has the full date&time and that you want to show three letter representation of a month in Spanish, then you’d do something like this:
$dateFormat(Fecha,M,es)
If it suppose to be a three letter representation of a day then D instead of M (php date format)
The dateFormat formula function and php date format is explained here - Xibo Documentation | Xibo Open Source Digital Signage
I see there is missing comma between format and language in the manual, we will get that fixed.
