hour() deluge function always return 0, how to get hour using deluge?

I am trying to get hour from Date/Time field like this

1. createdTime = lead.get("Lead_Creation_Time");
   
   hour = createdTime.getHour();
   
   info hour; // this line will returns '0'
   

but the result will always zero, I expect it will return '13'
