Hi @anjilinga It sounds like you might need to configure the format of your date field in the Index Pattern itself. There's an option to format date fields in Stack Management -\> Index patterns. If you select your index pattern and filter the fields list for 'date' fields, you should be able to configure the date format:

I hope that's what you mean by "not working", if it's not, could you please give a bit more detail as to what isn't working?
