    if "_grokparsefailure" in [tags] {		
		mutate {				
			remove_tag => ["_grokparsefailure"]					
		}				
	}

# Set Timestamp

mutate {
	add_field => {
		ExpectedTime => "03:00:00:000"
	}
}

mutate {
	add_field => {
		BusinesDateTime => "%{year}-%{month}-%{day} %{ExpectedTime}"
	}
}
#Not required ExptectedTime in output
mutate {
	remove_field => [ExpectedTime]
}

#Convert to Date
date
{
	match => ["BusinesDateTime", "YYYY-MM-DD HH:mm:ss.SSS"]				
}

#Adding one day to BusinessDateTime

ruby {
code => 'event.set("BusinesDateTime", LogStash::Timestamp.new(event.get("BusinesDateTime")+86400))'
}
```
